ON December 14, 1972, Eugene Cernan became the last astronaut (so far) to stand on the Moon’s surface.
Top ten things you did not know about the moon
1. He was the last man to leave the Moon but only the 11th of 12 to arrive there. Harrison Schmitt exited the lunar module of Apollo 17 after Cernan.
2. Although other planets have larger satellites than our Moon, the ratio of our Moon’s diameter to that of Earth is the largest in the solar system.
3. The Moon’s origin is unclear but the most likely theory is that it resulted from a collision between Earth and another planet over 4 billion years ago.
4. The hypothetical body that collided with Earth all those years ago has been given the name Theia, the mythological mother of Moon Goddess Selene.
5. The Moon is slowly moving further away from Earth at about 4cm a year.
6. The average gravitational pull on the Moon is only a sixth of that on Earth.
7. The same side of the Moon always faces Earth but only 41 per cent of its surface is never seen.
8. The highest point on the Moon is higher above its surface than Mount Everest on Earth.
9. Of the 12 men who walked on the Moon between 1969 and 1972, eight are still alive. They are all in their 80s.
10. “You seen one Earth, you’ve seen them all.” (Harrison Schmitt).
