Earth

Earth (also known as Dragon World and E-Arth) is a blue and green planet that rests in the Milky Way Galaxy. It is vastly inhabited with humans, remains of saibamen, Namekians, Saiyans, vampires, Majins, and more.

Climate
Earth is a planet in what is known as a Goldilocks Zone, a place in space that isn't too hot, or too cold. The temperatures in Dragon Ball Z's Earth ranges from a mild 70F in the summer and near 10F in the winter.

Earth has an extremely wide range of climates and precipitation, depending on the environment is present. Deserts can have sandstorms to just plain blazing heat, whereas Grasslands can have thunderstorms. Glaciers can have snow storms, whereas hurricanes can wipe off of the ocean and onto a landmass.

Planet
Earth itself rotates with a tilted axis, revolving around it's Yellow Sun and staying 149,597,870,700 meters (92,955,807 miles) from it due to gravitational forces, and has one moon. Earth has been destroyed twice (once from Kid Buu and another from Golden Frieza), yet revived with the Namekian Dragon Balls.

Unlike actual Earth, the Dragon Ball Z verison of Earth has one landmass and two island clusters (excluding Kame House). The sunrise and sunset can go from orange to pink, and the day sky is blue from the reflected light of the atmosphere. An Earth Day is 24 hours, and an Earth Year (which is the cooldown for the Earth Dragon Balls) is 365 Days.

Life
Earth's life is rumored to originate from cells, then evolved into humans. Humans are the native race of Earth. But ever since the tales of Son Goku and his friends, the place has become somewhat popular to nearly all the known universe.
