THE MOON

We always see the same side of the MOONCalled Synchronous rotation

Synchronous Orbit/Rotation

• * The time it takes the moon to rotate once is equal to the time it takes to orbit around the Earth once. 27.3 days

• The same side of the moon is ALWAYS facing the earth (called nearside).

• We cannot see the Farside from Earth. The 1st time humans saw Farside was 1959 (Soviet Interplanetary Satellite).

Farside!!!• Image from Apollo

16. Left side is part of nearside.

• Greater amounts of Craters and virtually no Maria (the dark portions easily visible on Nearside)!!!

Earthshine

• “dark side” of the moon is illuminated by the Earth’s reflected light.

• There are THREE kinds of eclipses!

• The moon is ¼ the size of the Earth, so the shadow does NOT cover the entire Earth.
