Earth (地球, Chikyū), also called the Dragon World
(ドラゴンワールド), is a planet inhabited by mainly Earthlings but other races
and species also reside on this planet. It is the home of the Z Fighters, and the main setting for the entire Dragon Ball series. It is also the main setting to the other Akira Toriyama's series, Dr. Slump and Nekomajin,[2] as well as the one-shots Wonder Island, Tomato, Today's Highlight Island, Pola & Roid, Escape, Pink, Dub & Peter 1, Go! Go! Ackman, Sand Land, Kajika, Oishii Shima no Ū-sama, and Jaco the Galactic Patrolman.
According to Whis, Earth is designated as "Planet 4032-877".[3][2]
Overview
Characteristics
Earth is Planet 4032-Green-877, and is part of the Seventh Universe.[2] It is a very advanced planet of the North Section (the Northern Quadrant of the universe) and within the administrative zone of Beerus the Destroyer.[2] Bulma says that Earth is at the edge of the section. The events that occur on Planet Earth are continually watched over from a neutral standpoint by King Kai (ruler of the North Galaxies) and the Supreme Kais (rulers of the whole universe). Flying vehicles, capsules that can shrink inanimate objects down to pocket size, robots, and other near-future science-fiction staples are commonplace on Earth. The architecture is also more advanced. The buildings are usually rounded, often employing spherical or ovoid sections held aloft by a cylindrical stem. Certain elements of magic also coexist with the advanced science.http://dragonball.wikia.com/wiki/Earth
