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.

Tir Planitia is a large plain on the planet Mercury. The name Tir (تیر) is the Persian word for "Mercury", and the name was approved in 1976. It was first observed in detail by Mariner 10. It lies between the large crater Mozart and the ancient Tolstoj basin.

Haystack Catena is a catena on Mercury. It superficially resembles a graben but is a chain of overlapping secondary craters. It is named after Haystack Observatory, and was originally named Haystack Vallis when it was imaged by Mariner 10 in 1974, but the name was changed in 2013 to better reflect its origin. It is approximately 274 km long. It is located near the center of the Kuiper quadrangle, and it is radial to a large, unnamed crater that is Tolstojan in age.

Bach is a double-ringed impact basin within the Bach quadrangle of Mercury. It was named by the IAU in 1976.

Michelangelo is a 230 km diameter impact basin in the Michelangelo quadrangle of Mercury, which is named after this crater. The crater itself was named by the IAU in 1979 after the Italian painter, sculptor and architect Michelangelo.

Vivaldi is a crater on Mercury. It was named by the IAU after Italian composer Antonio Vivaldi in 1976. It has a prominent and nearly continuous inner ring whose diameter measures about half that of the outer ring. It is one of 110 peak ring basins on Mercury. Unlike some of the lunar multiringed structures, no vestiges of additional rings are apparent around this crater. It is classified as c3 age.

Scarlatti is a pit-floored crater on Mercury, which was discovered in 1974 by the Mariner 10 spacecraft. It has a prominent peak ring, and it is one of 110 peak ring basins on Mercury. The crater floor is covered by the smooth plains material. The crater displays an arcuate collapse feature along the northeastern peak ring. The size of the pit, which was first noticed in MESSENGER images obtained in January 2008, is 38 × 12 km. Such a feature may have resulted from collapse of a magma chamber underlying the central peak ring complex of the crater. The collapse feature is an analog of Earth's volcanic calderas. Scarlatti is thought to have the same age as the Caloris basin.
