Planet Pluto Facts

1. As of 2006, Pluto is not longer considered a planet, but rather designated as a “dwarf planet,” meaning that it is a planetary-mass object being neither a planet nor a satellite. Pluto was declassified as a planet by the International Astronomical Union (IAU).

2. Pluto is the smallest dwarf planet in the Solar System, smaller than Earth’s Moon, and half the width of Jupiter’s moon, Ganymede.

3. Pluto’s journey around the Sun takes 248 Earth years. This means that, since its discovery in 1930, it still has over 160 years to go until it has made a complete orbit around the Sun.

4. Pluto’s atmosphere is composed of a thin layer of gas containing carbon monoxide, methane, and nitrogen. Its atmospheric pressure has been estimated to be 1/700,000 compared with that of earth.

5. Pluto orbits the Sun on a different plane than the 8 planets, going over them and below them.

6. Pluto has four identified moons, Charon, the largest is not much smaller than Pluto itself. (Pluto is 2,280 kilometers wide, Charon is 1,212 kilometers wide). The other 3 are Nix, Hydra, and newly discovered S/2011 P 1 on July of 2011.

7. A day on Pluto is equivalent to Earth’s 6 days and 9 hours, meaning that it has the second slowest rotation in the Solar System (after Venus, which takes 243 days to turn on its axis).

8. Pluto’s orbit is elliptical, meaning that it can come closer to the Sun than Neptune, but then go almost two billion kilometers further away from Neptune’s orbit.

9. Pluto is too faint to be seen with the naked eye. When viewed through a telescope, it looks like a star.

10. Pluto is cold: -233° C (-390° F), just 40° C (72° F) above absolute zero. At this temperature, all elements would be frozen except for neon, hydrogen, and helium.

11. Pluto maximum distance from the Sun – 7.38 billion km (4.6 billion miles).

12. Pluto’s minimum distance from Earth – 4.28 billion km (2.7 billion miles).

13. If you weigh 100 lbs, your weight on Pluto would be 7 lbs. (multiply your actual weight by .067).

14. When gazing at the Sun from Pluto it would appear as a tiny bright start because the two are so far away from each other.

15. According to some astronomers, Pluto used to be one of Neptune’s moons, but it somehow broke out of its orbit.

16. Pluto was first located by Clyde Tombaugh in 1930.

17. One of the reasons why Pluto was declassified as a planet was because there are asteroids in the solar system that are bigger than Pluto.

18. Since being declassified as a planet, Pluto’s technical name is now 134340.

    Pluto may be the ninth world in our solar program ever because it was found out. On the other hand, being a modest rocky planet having a really strange orbit, it does not truly fit in using the relaxation in the gaseous outer planets. Pluto is a lot a lot more comparable to some group of objects known as Trans-Neptunian Objects (TNOs), or asteroids. So, some astronomers do not consider Pluto need to be known as a planet.

    The International Astronomical Union (IAU) will get to choose inquiries for astronomers all around the community. They’ve been discussing Pluto’s standing, and what it will need to be labeled. Because Pluto is extremely essential to lots of men and women, the IAU isn’t gonna take away Pluto’s standing like a planet. They’re referring to calling Pluto equally a planet along with a TNO, but Pluto nevertheless is and will likely be a planet!

  2. katelyn

    i think this is a real planet. dont distribut them just because its small cold dark and icy…>.< thats just mean..and great website it really helped me win 1st on my science fair project!!!

  3. zapper

    ppl always think pluto is not a planet but it is along with ceris & eris

  4. cody aamold

    this website doesnt say anything about pluto and the distance from the sun

  5. Go educate yourself.

    For one, Pluto is not a planet.
    The actual definition of a planet is “A celestial body that (a) is in orbit around the sun (b) has sufficient mass for it’s own gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (i.e., the object is nearly spherical) and (c) it has cleared the neighborhood around its orbit (of smaller bodies).”

    And guess what? Pluto doesn’t achieve B or C. So you can all hope and dream that there are 9 planets, but by definition it is not. It was reclassified to a dwarf planet in 2006.

    I’m taking an astronomy course right now, so go ahead and say that “oh it’s still a planet.” all you want to, because the books, NASA, and everyone else has accepted the fact that it is not a planet. And if some little 14 year old doesn’t want to believe it, so they disagree, I don’t think they really care. All of you on here who write that it is a planet type like you have never been educated and are obviously like 12.

    Oh and for two, Pluto has 3 moons, not 1. They are named Charon, Nix, and Hydra.

  6. pluto girl

    they repeted number 6 its number 10 as well :(

  7. madison

    love this website it helped me with my science project and i thought pluto had 3 moons?????????????????!!!!!!!!!!!!!!!!!!!!!!! :D :D :D :D

  8. Michael Jackson

    WE ARE THE WORLD! WE ARE THE CHILDREN! Leave Pluto ALONE >:( He/she has feelings too :’( PEACE FOR ALL.

    THIS IS IT.

  9. J-Kwon

    Everybody in pluto get tipsy . wooo . weed all day .

  10. hannah and kierra l.

    thankyou so much me and my fren r gonna use this 4 our science project!

  11. Michellleee!!:)

    I hellla need this for school thanks. Astronomy is kinda boring but its awsome to think of all we have out there. But yeaa i agree with all the people.. Pluto should be allowed to be a planet. Once I wrote on a card saying “We will all miss you pluto! Your always a planet to me.” Then I tied it to a balloon and sent it off into the air. I know ofcourse its impossible for it to get to pluto, but it still meant alot!! Its the closest thing you can get to sending something to pluto. hehe you all should try it too. And im in school when im writing all this… im such a bada$$. hahha

  12. Kay

    Alright, “go educate yourself.” We all know now that Pluto is not a planet. We aren’t stupid people. This is information is obviously older information (since before Pluto was deemed a dwarf planet and before the other moons were discovered.) People make mistakes, we’re only human and everyone has their own opinion.

    No one cares if you’re taking an astronomy course or not. It doesn’t give you the right to come on and insult people because they choose to consider Pluto a planet still. You obviously need to grow up and learn that people have their own opinion and you don’t have the right to judge them by it.

  13. Lilly

    6.) and 10.) are nearly exactly the same fact! :) :):):)

  14. alex man

    HOWZ

  15. Chocolate Thunder

    Yeah heaps cool

  16. slim!

    eventhough pluto is the tiniest planet it is the best planet you could search and learn alot about it because its so unique. like we know he is far from the other planets but i will always be their next to it to be hes buddy(:

  17. Jonathan945

    Thanks who ever created this website, it really helped for my high school science project.

  18. cjr

    most of its copied and you reapet the same thing twice

  19. BWAKA FWAKA!!!!!!

    pluto was named after the roman god of death i think. to the greeks its hades

  20. Tom

    Pluto is a planet and one day i am going to colonize it and only people who think it is a planet can live there. then we will wage war on earth until they agree to sanction Pluto as a planet like it rightfully deserves.

  21. not american

    I’m guessing you guys are mainly Americans, because you are being slightly stupid.
    Stop treating Pluto like a person, somebody said it is being mean to call pluto not a planet. it isn’t mean, it’s true! Pluto is too small, it’s either a massive stationery comet or a Dwarf Planet! Get your Facts right!

  22. danny

    Whoever wrote these “facts” Go back to school!!!! and fact 9 is kinda stupid go over it carefully and see the non sense it makes

  23. Lilly ki

    Im late it is dec and all the other comments r in march

  24. ally

    pluto isso cold that even oxegen would be frozen :(

  25. Able

    Dis is cool. i love this site. when was pluto made?

  26. da' alien

    I love this but Pluto’s surface is frozen cause it’s so far away from the SUN. Indicating it might have a surface but a frozen one!

  27. Collette

    Hi, I am Collette(obviously) I’m currently in 7th grade and I think this website should be updated yearly. This was made 10yrs ago (today is 2/2/2011) and the info isn’t correct anymore. Pluto now has 167 years to go. DO THE MATH! 2011-1930=81 248-177= 71(not 81) 177-10= 167yrs to go till one plutonian year has passed since discovery. That and other info needs to automatically be refreshed AT LEAST every year.
    Please take my concern to heart,
    – Collette Kent

  28. McKenna

    Great site!!! Mistake # 8 Pluto has 3 moons Charon, Hydra, Nix

  29. JD4LIFE

    THIS WEB SITE IS COOL IT TELL YOU ABOUT DIFFRENT STUFF WAT PEOPLE SAY AND I LIKE TO DO RESERCH ON DIFFERNT PLANETS LIKE MARS AND MORE EARTH MY MATH TECH ME ALL ABOUT EARTH HOW BIG ITS IS AND SMALL WELL SOME TIMES I THINK THE EARTH IS BIGGER THAN THE ANTHER STATES BUT ITS NOT EARTH IS A LIKE IN THE MIDEL OF EVERY THING LIKE ME I LIKE TO READ BOOKS ABOUT DIFFRENT PLANETS AND TELL ME WAT YOU LIKE.

  30. koko

    you need more fact like why it is not a full planet any more i know it is a miner planet

  31. peaps

    next time PUT DAY LENGTH AND MASS,YEAR LENGTH,MILES WIDE, ATMOSPHERE,AND KNOWN MOONS GOT IT ok

  32. stanley

    pluto isn’t a planet maybe scientist saw it wrong maybe it was actually this way maybe charon was the planet and pluto was the moon maybe they saw it wrong

  33. Yenghoua

    Pluto is color grayish blue.

  34. $$ MaTtY.g 001 $$

    PLUTO IS NOT A PLANET ANY MORE, IT DOES NOT EXIST!!!!!

    “I’m taking an astronomy course right now, so go ahead and say that “oh it’s still a planet.” all you want to, because the books, NASA, and everyone else has accepted the fact that it is not a planet.”

    Go Educate Yourself, how about YOU educate YOURSELF before repeating one side of an ongoing debate as fact when it is not. The rules you cite are very much still a matter of controversy and are not accepted by many astronomers. Only four percent of the IAU voted on this, and most are not planetary scientists. Their decision was immediately opposed by hundreds of professional astronomers in a formal petition led by New Horizons Principal Investigator Dr. Alan Stern. In fact, Stern is the person who initially created the term dwarf planet to designate a third class of planets in addition to terrestrials and jovians, small bodies large enough to be pulled into a round shape by their own gravity but not large enough to gravitationally dominate their orbits. He never intended for dwarf planets to not be considered planets at all. The best books, teachers, and educational materials are those that teach the controversy rather than portraying only one side of this ongoing debate as fact.

    Also, Pluto is not a comet. It is much larger than any comet, and its orbit never takes it into the inner solar system. It is very likely geologically differentiated into core, mantle, and crust, just like the Earth. No comet is geologically differentiated. Comets are largely composed of ice while Pluto is 70-75 percent rock.

  38. talia

    hay i really want 2 have a picture of of pluto so i can put the picture on my science project can anybody can help?

  39. talia

    this site kinda DIDNT help with what im lookking forr..i need the common elements and their states of matterr!!?

  43. john

    damn i would only be 15 pounds on that planet <3

  44. chels

    victoria you are wrong you are lying pluto has three moons charon nix and hydra i dont know what the heck your talkin bout but your wrong and get your facts right!!!!

  45. chels

    UPDATE THIS WEBSITE!!!!!! first of all people that are postin that pluto is a dwarf planet you need to also get your facts right and you need to update ok listen everyone on august 24 2006 pluto was named a dwarf planet on june 11 2008 it was named a plutoid!!! stop saying its a dwarf planet its a plutoid and god some people need to watch there freakin language there are kids on here like me im in 5th grade!!!! watch it and if you are in middle or high school and your saying its a dwarf planet gosh you guys are idiots again i am ten in fifth grade learn more and watch your mouth!!!

  46. James

    Pluto is a planet. I love it a lot. Don’t you agree? Pluto is a nice planet even though it is cold it is still great. It’s wonderful really. And thank goodness you thought Pluto was a planet. Even though people say Pluto isn’t a planet…it still is. Even though it is the ninth planet in the solar system, it feels like it is one mile away from earth.
    To Pluto:
    From James.
    PS. Pluto is cute.

    nerds!!!! i’m doing this for school

  51. sexy beast

    this website sucks

  52. Taron

    I think it is a planet because just becuse it is small and the farthest from sun so it is a PLANET PEOPLE BELIVE ME!!!!!!!!!!

  53. kayden

    i think pluto is not a planet because all the other planets have thier own orbits

  54. james

    Pluto is a planet, don’t you guys get this?
    Why are there so many comments that say Pluto is not a planet? Or even worse, just talk about the website. Please, I want more people saying Pluto is a planet. It is my favorite planet in the universe. Don’t you guys get this? I’m getting so mad. If Mercury got kicked out of the solar system, there would be just like 4 comments. And the same with like Neptune, not be a lot of comments. I’m so mad with the people that don’t call Pluto a planet. And Pluto does exist!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  55. Marc

    @james;
    I DONT LIKE IT EITHER, but if you look at the facts, making Pluto a Dwarf Planet IS justified. There are actually BIGGER objects orbiting in the Kuiper Belt, which is where Pluto resides, like Eris, which is 25% bigger than Pluto. If they classified Pluto as a planet, they would have to do the same to many more objects in the Kuiper Belt!
    One thing I think they HAVE done wrong is not to classify Pluto a Binary Dwarf Planet, Which it is! Pluto and Charon orbit each other, with Charon being approx 50% of Pluto’s mass. they orbit a point just above Pluto’s surface. Making them a Binary System.

    P.S. Did anyone else notice fact number 6 and fact number 10 are EXACTLY THE SAME!?!

    :)

  61. girlcool

    i can not believe that pluto is a drough planet now so freaken cool man!!!!! so i need to see more :)

  62. Laurel Kornfeld

    Pluto is still a planet, as are Ceres, Haumea, Makemake, and Eris. Only four percent of the IAU voted on this, and most are not planetary scientists. Their decision was immediately opposed in a formal petition by hundreds of professional astronomers led by Dr. Alan Stern, Principal Investigator of NASA’s New Horizons mission to Pluto. Stern and like-minded scientists favor a broader planet definition that includes any non-self-luminous spheroidal body in orbit around a star. The spherical part is important because objects become spherical when they attain a state known as hydrostatic equilibrium, meaning they are large enough for their own gravity to pull them into a round shape. This is a characteristic of planets and not of shapeless asteroids and Kuiper Belt Objects. Pluto meets this criterion and is therefore a planet. Under this definition, our solar system has 13 planets and counting: Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto, Haumea, Makemake, and Eris.

  63. Melody

    This was a very helpful website for my Science project, and it was just cool to learn the facts. Btw PLUTO IS STILL A PLANET!!!!!!!!!!! I’m not saying that everyone said that

  64. Miss.Daisy

    This is a very helpful website.It helped me with my Science project which is due tomorrow.

  65. Malissa

    It would be nice to update this site because Pluto isn’t the ninth planet anymore….Ask someone and update your site before you put it on the internet please… thanks. Oh, and by the way… It would improve your site like MAJOR! if you updated it once in a while and actually read the comments and found proof on the internet. Some people hear are aware of more facts then you I’m sure. So please check the comments once and a while and update the site. And, I’m just guessing here, either this site is really old and hasn’t been updated or the person previously made this site and just doesn’t believe Pluto is not a planet. Some people still believe that. So yeah. Update, revise, re- look (for more facts ) and read comments ( let your viewers know you care…. if you do care O_O) -Viewer :D but over all the ” need update ” facts this is a pretty good site :) good job! but still improve.

  66. jackson

    pluto has 4 moons

  67. HaterGirl

    Hey people :D gonna post some of my own Pluto facts…….. Enjoy & Comment!

    1.Pluto is the second biggest known dwarf planet in our solar system, after Eris.
    2.It has an axial tilt of 120°
    3.Pluto’s atmosphere consists of nitrogen, methane, and carbon monoxide gases

    I might post more…. I love this website!

    4.Internal structure: Probably a rocky core surrounded by a mantle of water ice, with more exotic ices such as methane and nitrogen frost coating its surface.
    5.It remains unknown whether Pluto has a magnetic field, but its small size and slow rotation suggest it has little to none .

    Comment about my Comment and maybe I’ll post more!

  69. MissSparklyHaterGirl

    was reading these comments……
    pluto actually has 4 moons katelyn, not 3

    I <3 this website!

  70. iLikePie

    Pluto isn’t a planet. If so call Jupiter the 6th planet because Ceres will be the 5th. Infact there would be about 14 (If you include 2003UB131). Demoted in 2006 because Eris was found and slightly smaller objects in the Kuiper Belt. Pluto is a Kuiper Belt Object along with 2003UB131, Eris, Makemake and Haumea. Just except it. A Dwarf Planet unless you’re used to the Plutoids, Eris, Haumea, and Makemake, making Ceris the only Dwarf planet.

  74. Feli

    Cool stuff

  75. Jim Pallutto Sr.

    Is there a possibility that Pluto will add enough mass to actually achieve planetary status again? If not, is there anyplace where another planet could form or is our solar system too developed for this possibility?

  76. tata

    wow this r the most intresting factsi really lke this site. i no it sonds neeky but it really is intresting lool, i think i’m ganna coe on thi site eveyday lool :)

  77. 9

    In the ‘Atmosphere of Pluto’ article, it states that “The ices on the surface of Pluto derive nitrogen, methane and carbon monoxide gasses.”

    In other articles on this site, it states there are traces of “Nitrogen, methane, and /carbon dioxide/ gasses, not carbon monoxide.

    This is a great site, but some of the information is either inconsistant or stated way too many times over. There are also a few facts on here that should be updated, and it would be nice to know the year this was posted, so any dates could be compared to the present date.

    Also, it is very controversal about wether or not Pluto is a planet or a dwarf planet. It is still a largely debateable concept, so instead of taking one site as if it is truely and officially accepted, it would be more correct to stay away from stating ‘the planet’ or ‘the dwarf planet.’ (Which, is also, as stated above, inconsistant. Some articles on this site state Pluto as a planet. Others state it as a dwarf planet).

    Once again, this is a very good site for information, but I do not believe all of this to be true/ fully correct. A review and revision of the whole site would be appreciated.

    this saved my butt for my science project on pluto

  79. musicgirl

    glad i found this website

  80. sarah

    this website rocks!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! my teacher suggested it. she is soooooooooooo awesome!!!!!!
    did you know that pluto was not considered a planet anymore because crossed neptune’s orbital plane??????

  81. Amber_A203148910

    I have always wanted to find out more about pluto & all of the other planets. I love to study science & find out about things like neptune. I got a 100% on an assignment about neptune. pluto is actually a planet IF u want to include it like all the other planets. Do u agree? Does anyone or has anyone found out anymore information about the new planet they found. they say that it looks just like earth.

  82. 00156803200003050911

    I like figuring out about planets & the galaxy to. I agree with Amber_A203148910. She has a good point. Anyone agree? I also like finding out new things & studying science. Who else knows about pluto, neptune or the new planet that looks like earth? jw. I mean i dnt even know about the new planet yet. Do u think 2012 is true?! (jw. idk about it either). <– do u think its real!?

  83. Andyj

    Web pages like this need constant revision. They have now found a fifth moon orbiting Pluto. Carbon monoxide???

    As far as I’m concerned if it has any atmosphere, moons, sea’s, ice and round enough, it ha to be labelled a planet.

    I call Pluto a planet who’s only reason for demotion by a bunch of stiff necked elitists was it’s discovery was done by a non-qualified man doing the donkey work.

  84. Lauren

    here is some more info:

    From where was Pluto discovered?

    Pluto was discovered from Lowell Observatory in Flagstaff, Arizona It was founded in 1894 by astronomer Percival Lowell.
    Lowell Observatory is among the oldest observatories in the United States.

    Who discovered Pluto?

    Astronomers noticed that the orbits of Neptune and Uranus were being affected by the gravity of an unknown object in this solar system.
    Percival Lowell spent most of his career in the search for Planet “X.”
    Pluto was discovered in 1930 by Clyde Tombaugh.

    Astronomers noticed that the orbits of Neptune and Uranus were being affected by the gravity of an unknown object in ths solar system. Clyde Tombaugh carefully studied images of the night sky and after a lot of hard work he finally discovered Pluto. Clyde Tombaugh was only 24 years old when he made this discovery.

    Does Pluto have moons?

    Pluto has three known satellites (Hubble Telescope), the largest of which is Charon.
    Charon’s diameter is over half the diameter of Pluto, making Charon the biggest moon with respect to the planet it orbits.

    What does Pluto look like?

    Some of the detail that is visible on Pluto (Hubble Telescope) is the presence of polar ice caps as well as large dark spots near the equator.
    The surface temperature of Pluto varies between -391°F and -346°F. The ” warmer” temperatures loosely correspond to the darker areas.

    What is Pluto?

    It has been discovered that Pluto is one of the largest of tens of thousands of objects made of ice, rock, and dust.
    A new mission called New Horizons was launched in 2006 and is expected to fly by Pluto in 2015 and provide much needed information about Pluto.

    What is the Kuiper Belt?

    Discovered in 1992
    Similar to the asteroid belt, although it is far larger—20 times as wide and 20 to 200 times as massive
    remnants from the Solar System’s formation
    Frozen methane, ammonia, and water

    What is the Oort Cloud?

    No confirmed direct observations!
    A hypothesized spherical cloud of comets which may lie roughly 50,000 AU, or nearly a light-year, from the Sun

    Although no confirmed direct observations of the Oort cloud have been made, astronomers believe that it is the source of all long-period and Halley-type[] comets entering the inner Solar System and many of the centaurs and Jupiter-family comets as well.6 The outer Oort cloud is only loosely bound to the Solar System, and thus is easily affected by the gravitational pull both of passing stars and of the Milky Way Galaxy itself. These forces occasionally dislodge comets from their orbits within the cloud and send them towards the inner Solar System.3 Based on their orbits, most of the short-period comets may come from the scattered disc, but some may still have originated from the Oort cloud.36 Although the Kuiper belt and the scattered disc have been observed and mapped, only four currently known trans-Neptunian objects—90377 Sedna, , , and —are considered possible members of the inner Oort cloud.
