| gptkbp:notable_work |
Ceres has a complex surface geology
Ceres has a large crater called Occator Ceres has a thin atmosphere Ceres has a unique surface composition Ceres has bright spots of sodium carbonate Ceres shows signs of cryovolcanism Vesta has a large impact crater called Rheasilvia Ceres has a complex history of impact events Ceres has water ice on its surface Ceres may have a subsurface ocean Vesta has a differentiated structure Vesta is believed to be a remnant protoplanet. Vesta's equatorial region is heavily cratered Vesta's poles have different geological features Vesta's surface is covered in basaltic rock Vesta's surface shows evidence of ancient water activity |
