A Planet is a celestial body in space that normally orbits a star.
The definition of what is constituted a planet varies, but normally planets are considered to:
- orbit a star,
- not orbit another celestial body that isn't a star nor a binary star,
- not have any other objects (other than a moon) share its orbital region unless smaller objects were pulled in by its orbit.
There are two types of planets in the galaxy: gas giants and terrestrial (or rocky) planets. The former normally being the largest type of planetary classification.
Planets also host a multitude of atmospheric conditions and sizes.
