Interesting facts about the moon
Rotation of moon
The same side of the Moon always faces the Earth. The Moon's rotation period is synchronous with its revolution period around the Earth.
Change of distance
Because of a loss of orbital energy to gravity from the Earth, the Moon is very gradually moving away from the Earth. In the very early history of the Earth, the Moon looked about 3 times larger in apparent size in the sky, because it was closer to the Earth.
Lunar atmosphere
The Moon has almost no atmosphere, because of its weak gravity. All types of gas will escape from its surface.
Without an atmosphere, there is no wind or water erosion. The Moon's surface is about the same now as it was 3 billion years ago. The astronauts' footprints remain unchanged on the Moon's surface. The footprints should last at least 10 million years.
