Petronius is a crater on Mercury. It has a diameter of 36 kilometres (22 miles). Its name was adopted by the International Astronomical Union (IAU) on the August 6, 2012. Petronius is named for the Roman author Petronius.[1][2]
Petronius has a region of permanent shadow on much of its floor, which has a bright radar signature. This is interpreted to represent a deposit of water ice.[3][4]
