Planets

 __//**PLANETS**//__
 * Planets** are defined as a **celestial body** that orbits in a circular motion around a star. They form around the star which one day they will orbit around. They form from gases and dust rings which swirl around the star and form young planets(young planets are also known as planetesimals) which will attract more matter to eventually become planets. There are 2 types of planets. One is terrestrial planets, much like our own planet Earth. Terrestrial planets are planets which mainly are composed of rocks and metals. The other type of planet is **Jovian planets**, which are mainly consisting of gases such as hydrogen and helium. A good example of this is Jupiter. Jovian planets usually are just big ball of gases which have condense together in a ball. Terrestrial planets on the other hand condense and form rocks which then stick and connect together in a spherical ball but it is not completely symmetrical. A good example of how they form are like dust balls which form under your bed.

Our system of planets contains **8 planets** after **Pluto** was classified as a dwarf planet along with Eris and Ceres.

There is a very good chance thats life exist on other planets just like our own. But not every planet can have life on it, because some planets are Jovian planets and they do not have suitable conditions for sustaining life. Other factors which may make are planet unsuitable for life is the location of where it is away from the sun. The planet has to be in a position thats is not too hot or too cold like earth. Another reason planets may contain life is because that we ourselves live on a planet.

Our Universe's planets (in order from closest to furthest away from the sun):
 * Mercury
 * Venus
 * Earth
