Crater 2 is a dwarf galaxy discovered orbiting the Milky Way,[1] located approximately 380,000 ly from Earth.[2] Crater 2 was identified in imaging data from the VST ATLAS survey.[2]

The galaxy has a half-light radius of ∼1100 pc, making it the fourth largest satellite of the Milky Way.[1] It has an angular size about double of that of the moon.[2][3]
