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] Jezža is on the floor of Argyre Planitia between the craters Hooke and Galle.[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]
