 It was launched by the Soviet Union January 31, 1966, and returned photographs of the lunar surface for three days.

The gravity of the earth keeps the moon in its orbit

The average distance of the moon is about 384,000 km.

Each complete trip of the moon around the earth is called a revolution

Each complete spin= rotation
