It was referred as the first satellite of Jupiter. Europa is the second moon of the four. […]

Gas Giants

Gas Giants

Are there planets that are not composed of rock, like Mercury, Venus, Earth and Mars? Are there planets where there is no land, just all nothingness? Yes, there are, they are known as a Gas Giants, they are large celestial bodies that are instead made up of gases. They may have a solid core, and their storm-laden atmosphere is very thick. They are all so large they could fit ten Earths.

Jupiter is considered to be a gas giant, which means that the planet is of huge atmosphere, has liquid solid core and liquid mantle without definite boundaries in between layers. It is actually the fifth planet away from the sun and the largest planet in our solar system. It is considered as a giant planet since if we combine all the sizes of the different known planets; it appears that Jupiter is still 2.5 times of all the mass combined. […]

Moons of Jupiter

There have been 63 moons discovered hovering around Jupiter. It is divided into different groups: the Main group or Galilean moons, the Inner satellites or Amalthea group, the Himalia group, the Carme group, the Anake group and the Pasiphae group. Three known satellites are not member of any group – Themisto , S/2003 J2 and S/2003 J3.

The Atmosphere of Jupiter

The Atmosphere of Jupiter

Jupiter’s atmosphere is the largest in the Solar System. Molecular Hydrogen and Helium make up most of its atmosphere as well as small amounts of ammonia, methane, hydrogen sulfide and water. Gases such as nitrogen sulfur, noble gas and oxygen can also be found in the planet. The gaseous part of the atmosphere slowly transitions into the liquid part of the planet. There is no clear division of the two.

Rings of Jupiter

Rings of Jupiter

Jupiter Rings, or the Jovian Ring System, is the third planetary ring system to be discovered after Saturn and Uranus. It was first seen by astronomers through the Voyager 1 space probe in 1979. After a decade, the Galileo orbiter was sent to further investigate the rings. Since then, it has been studied with the help of the Hubble Space Telescope by astronomers.

Who Discovered Jupiter

Jupiter is the Solar System’s largest planet, which makes its name quite appropriate. So while it isn’t the brightest object in the sky at night, its size makes it visible to the naked eye. Because of this, even the people from the pre-historic period knew that Jupiter existed. Of course, it took a while before they realized what Jupiter was.

What is Jupiter Made Of?

What is Jupiter Made Of?

Jupiter, the fifth and largest in our Solar System is comprised mostly of helium and hydrogen. Since these elements are the very same stuff that we would find in the Sun as in other stars, many people often wonder why this planet is not classified as such. The explanation for this is simple; Jupiter is not big enough to be one.
