Tempel is the remnant of a lunar crater whose outer rim has been eroded, indented, and reshaped by subsequent impacts and lava flows. It is attached to the eastern rim of the crater Agrippa, in an area that has been resurfaced by old lava flows. To the southwest is Godin, and to the east lies the small, bowl-shaped Whewell. There is a gap in the northwestern rim that forms a protrusion that follows the rim of Agrippa. (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.
