Morrison is a crater on Mercury. Its name was adopted by the International Astronomical Union in September 2022. Morrison is named for the American author Toni Morrison, who lived from 1931 to 2019.[1]
Morrison has a region of permanent shadow along its southern rim, which has a bright radar signature. This is interpreted to represent a deposit of water ice.[2][3]
To the south of Morrison are the craters Mansart and Bjornson. To the north are Rizal and Josetsu. To the east is Despréz.
