Welcome back to our series on Colonizing the Solar System! Today, we take a look at the largest asteroid/planetoid in the Main Belt – Ceres!
Between the orbits of Mars and Jupiter lies the Solar System’s Main Asteroid Belt. Within this region, it is estimated that there are over 150 million objects that measure 100 meters (330 ft) or more in diameter. The largest of these is the dwarf planet Ceres (aka. 1 Ceres), the only body in the Main Belt that is large enough – 940 km (585 mi) in diameter – to have undergone hydrostatic equilibrium (become spherical).
Because of its important location and the amenities this dwarf planet itself possesses, there are those who have proposed that we establish a colony on Ceres (and even some who’ve explored the idea of terraforming it). This could serve as a base for asteroid mining ventures as well as an outpost of human civilization, one which could facilitate the expansion of humanity farther out into the Solar System.

We continue our “Definitive Guide to Terraforming” series with a look at another body in our Solar System – the dwarf planet Ceres. Like many moons in the outer Solar System, Ceres is a world of ice and rock, and is the largest body in the Asteroid Belt. Humans beings could one day call it home, but could its surface also be made “Earth-like”?
In the Solar System’s Main Asteroid Belt, there are literally millions of celestial bodies to be found. And while the majority of these range in size from tiny rocks to planetesimals, there are also a handful of bodies that contain a significant percentage of the mass of the entire Asteroid Belt. Of these, the dwarf planet Ceres is the largest, constituting of about a third of the mass of the belt and being the sixth-largest body in the inner Solar System by mass and volume.
In addition to its size, Ceres is the only body in the Asteroid Belt that has achieved hydrostatic equilibrium – a state where an object becomes rounded by the force of its own gravity. On top of all that, it is believed that this dwarf planet has an interior ocean, one which contains about one-tenth of all the water found in the Earth’s oceans. For this reason, the idea of colonizing Ceres someday has some appeal, as well as terraforming.
