Earth is a planet of the Solar system and the home-world of humanity. Earth is moving around the star with the official name Sol but commonly referred to as the Sun. Earth has one physical satellite with the name Luna (usually referred to as "the Moon"), however, it is argued that Earth and Moon are actually a single system, since they both revolve around the common center of mass, rather than one around the other.
3/4 of Earth surface is water. Humans live in the rest 1/4 and have polluted it so much that it is doubtful whether future generations will be able to live as people have in the past.
There are many societies on Earth, most notable are these of humans, but also ants, bees etc.
Earth is 1 AU away from the Sun.
