Colonization of Ceres : ウィキペディア英語版 | Colonization of Ceres
The dwarf planet Ceres has been proposed as one possible target for human colonization in the inner Solar System. == Physical conditions ==
Ceres is a dwarf planet in the asteroid belt, constituting about one third of the mass of the whole asteroid belt and being the sixth-largest body in the inner Solar System by mass and volume. It has a round shape, and a surface gravitational acceleration about 2.8% that of Earth. It has a surface area approximately 1.9% of Earth's dry land, slightly larger than the total land area of Argentina. Observations indicate that it contains large amounts of water ice,〔(Bjorn Carey. Largest Asteroid Might Contain More Fresh Water than Earth )〕 about one-tenth of the total water in Earth's oceans. The solar irradiance of 150 W/m2 at aphelion, one ninth that on Earth, is high enough for solar-power facilities.〔
