Moon Basic Facts:• The mass of the moon is about 1/100th that of Earth.
• The moon has little or no atmosphere.
• The moon has a low density compared to the Earth.
• The moon revolves around the Earth once every month.
• The moon rotates on its axis once every month.
• Therefore it is said to be in synchronous rotation. (We only see ONE side of the moon from Earth!)

FYI (no need to memorize this):
•The Earth-moon system is evolving.
•The moon is moving outwards.
•The Earth is slowing down.
•Eventually, the moon will only see one face of the Earth.
•The timescale for this to occur on is...

Should we go back?
Are manned missions worthwhile?
The Apollo program sent people and spacecraft to the moon from 1968-1972. No spacecraft have landed on the moon since.

The Moon: Take-away messages
•The phases of the moon are caused by the relative locations of the Earth, moon and sun.
•Tides are caused by the gravitational pull of the moon.
•The moon is in synchronous rotation- we only see one of its faces.
•The moon was formed by a giant collision, followed by the collection of impact debris.
•Geology on the moon is controlled by collisions and volcanism (but the volcanism is different from that on Earth)
•Cratering on the moon can be used to understand collision rates in the solar system.
