| Eponym | Homer |
Homer is a crater on Mercury. It is one of 110 peak ring basins on Mercury.[1] It is Tolstojan in age.[2]
Deposits of material in and around this crater suggest the possibility of explosive volcanic eruptions at some point in the planet's history.[3] An unnamed crater in northwestern Homer (about 18 km diameter) contains hollows and has dark ejecta.
The crater name was approved by the IAU in 1976.[4] The naming of Stark Y crater on the Moon, located northwest of Stark, as Homer, was not approved by the IAU.[5]
The small but fresh crater Dominici lies along the northern margin of Homer. The crater Handel is to the northeast, and Titian is to the southwest.
