Jezža is a crater on Mars, located at 48°48′S 38°00′W / 48.8°S 38°W / -48.8; -38 in the Argyre quadrangle. It measures approximately 9.1 kilometers in diameter and was named after a town in Russia.[1] Jezza is on the floor of Argyre Planitia between Hooke Crater and Galle (Martian crater).[2] Other features surrounding it are Horarum Mons further south, Argyre Cavi to the west, and the tiny crater Delta to the north-northwest[2]

Impact craters generally have a rim with ejecta around them, in contrast volcanic craters usually do not have a rim or ejecta deposits. As craters get larger (greater than 10 km in diameter) they usually have a central peak.[3] The peak is caused by a rebound of the crater floor following the impact.[4] Also present are a few gullies in parts of the crater rim.
