Appearances can be very deceptive. The Teneriffe mountain range seem much less prominent than the the isolated Pico to the south east, but in fact both reach the same height of 2.4km above the surface of the Mare Imbrium. It was once thought that the Moon's low gravity would mean steep mountains, but Pico is at best one sixth as tall as it is wide.
