Eddie Crater is a crater in the Elysium quadrangle of Mars at 12.3° north latitude and 217.9° west longitude. It is 89 km in diameter and was named after Lindsay Eddie, a South African astronomer (1845–1913).[1]
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, as this crater has.[2] The peak is caused by a rebound of the crater floor following the impact. It contains material uplifted from beneath the surface.[3]
