Named after Hans Egede - Danish natural historian (1686-1758).
Egede is the remains of a lunar crater that has been flooded by lava, leaving only the somewhat polygonal circumference of the rim protruding just above the mare. It is located on the southern edge of the Mare Frigoris, to the west of the crater Aristoteles. To the southwest is an arc of low mountains curving. The floor is flat and nearly featureless, except for a few tiny craterlets, including secondaries from Aristoteles (wikipedia entry)
A crater is a circular depression likely created by an impact event. On the Moon they are named after deceased scientists, polar explorers, astronauts or cosmonauts.
