An artist’s impression of the two theories on how Ceres formed. In the first image, Ceres formed in the main belt and ammonia was incorporated from the external zones of the Solar System. In the second, Ceres itself was formed in the external zones of the Solar System, including ammonia in its formation process, and then migrated to the main belt. (Image credit: L.Giacomini)
The dwarf planet Ceres may have formed from minerals found in the outer Solar System, according to data taken by the Dawn Spacecraft.
Researchers identified specific minerals, which are widespread on the planet’s surface. The minerals suggest ammonia was incorporated into the planet during its formation.
