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]

The InSight Mars lander landed south and west of Eddie crater in 2018.
