The Moon - Lunar Orbiter 4
Mare Orientale basin on 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 outermost 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.
