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.

<span class="mw-page-title-main">Scarlatti (crater)</span> Crater on Mercury

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.
