Jezža (crater)
Jezža is a crater on Mars, located at in the Argyre quadrangle. It measures approximately 9.1 kilometers in diameter and was named after a town in Russia. Jezža is on the floor of Argyre Planitia between the craters Hooke and Galle. 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. The peak is caused by a rebound of the crater floor following the impact.
