The Moon - Lunar Orbiter 4

Mare Orientale basin on the Moon

The Moon
Lunar Orbiter 4 image of the Mare Orientale basin on the Moon. The basin forms a giant "bulls-eye" on the western limb of the Moon. Three distinct circular rings can be seen. The outer most is the Cordillera Mountain scarp, almost 900 km in diameter. The basin was formed by a giant impact early in the Moon's history. The north pole is towards the top.
