NASA’s Dawn spacecraft was the first to visit a dwarf planet earlier this month. Ceres, the 940 km diameter planet visited, makes up a quarter of the mass of the asteroid belt. Because of it’s extremely low gravity (0.29 m/s versus 9.81 m/s on Earth) and proximity to the resources in the asteroid belt, Ceres is considered a good candidate for a future outpost. Orbiting 445,410,000 km (the Earth is at only 151,930,000 km) from the sun, it would be a distant
A short composite video was prepared by NASA from photos taken by the Dawn spacecraft and can be seen here. The video shows the rocky, pitted surface of Ceres.
