1. The Sun is a star that is in the center of the Solar System 2. The Sun is recognized as having the largest mass in our Solar System. 3. The diameter of the Sun is 1.4 million km (870,000 miles) 4. The Sun’s distance from the Earth is 150 million km (93 million miles) 5. Earth orbits the Sun 365 days, yes, one year. 6. The Sun rotates every 25-36 earth days. 7. The Sun’s energy travels outwards. 8. [...]

The planet Pluto is named after Hades, the mythological Greek god known as the ruler of the underworld. After gathering suggestions and experiencing several debates, the planet was named Pluto partly because it is very far from the sun. The planet is perpetually dark. Another reason for its name is because PL are Percival Lowell’s initials, the man who theorized that another planet existed. The planet was discovered in 1930.

Planet Mercury is the planet that is considered as the closest to the sun and orbits the star for about an average distance of 57.9 million km. It can make a complete trip around the sun for a period of 88 days. Now that Planet Pluto is already referred to as a dwarf planet, Mercury has already been tagged as the smallest planet present within our solar system. Its diameter is only measured at about 4879.4 km but despite the [...]

Also called the Blue Planet (due to its color when seen from outer space), the World, and Terra (a Latin term), the Earth is the planet fourth from the Sun. As any elementary school student could tell you, from that order, the Earth is preceded by Mercury and Venus. And as you may have surmised the moment you gained conscious of the world, Earth is the home to humans and millions of other species—the only planet in the solar system [...]

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. [...]

Mercury is the planet that is closest to the sun. It is also the smallest. These two factors make it hard for experts to thoroughly probe Mercury. So far, only two spacecrafts have flown to Mercury to collect data: the Mariner 10 during the 1970s and the MESSENGER spacecraft in 2008. Still, even with these two probes, there hasn’t been a complete mapping of Mercury. The MESSENGER will return in 2011 to map the planet’s entirety, only no one knows [...]

Our home planet, Earth, is considered as the biggest one when it comes to terrestrial planets. Terrestrial planets are described as dense planets located within the solar system. This planet is just right for living things. The temperature, the atmosphere and weather conditions are just enough to sustain life and keep all living things breathing. The planet has one moon named as Luna.

Jupiter is known by everyone specifically for one thing: it is the solar system’s largest planet. It is also one of the planets visible to the human eye. Like three other planets, Jupiter is a gas giant. It is also named after the one of the most significant figures in Roman mythology—Jupiter (also known as Zeus in Greek mythology). Next to the Moon and the planet Venus, Jupiter is the brightest object in the sky at night (although it can [...]

The planet Neptune has features that other planets don’t have. It is far from Earth in which it can be compared to a tiny star when being observed through the use of binoculars. It is said to be brilliantly blue. When we are viewing planets in the sky at night, we actually see the light that is reflected off of these planets from the sun. Due to this, it can be ascertained that reflected sunlight is also seen from Neptune. [...]

Asking who discovered the Earth may seem like a silly question—but it isn’t. After all, what is there to discover, if the very first humans lived on the planet anyway? But while this is the case, it took some time before people actually recognized the Earth, the fourth one from the Sun in the Solar System and the only one known to have existing life, is a planet. This makes sense considering the various theories regarding the status of the [...]
