1. The moon is the only astronomical body whose distance from the Earth can be measured in thousands of kilometers. Long before the dawn of written history the Moon was paid much attention to by man who was interested and attracted by the presence in the sky of a planet that was so clearly seen from the Earth.
2. In the middle ages the moon was supposed to have a smooth crystalline surface like a mirror and that the dark spots on the Moon were accounted for1 by the fact that the Earth was reflected on its surface. However, with the help of the first little telescope that was turned by Galileo upon the Moon this conception was put an end2 to as early as3 1609. Galileo thought that he saw mountains and valleys, seas and continents on the Moon.
3. The view of the Moon has been obtained with the help of a series of automatic lunar stations named “Luna”.
4. Having been transmitted by these stations, the photos and panoramas have shown that the surface of the Moon is uneven and rugged, with many hills and cavities like volcanic craters, a few of them measuring some kilometers in diameter. A great number of stones lying on the Moon’s surface proved the lunar ground to be firm enough and it would not sink if it were stepped on, walked across or put some heavy weight upon. Man’s knowledge of the Moon is rapidly progressing, new data being constantly reported.
5. The mutual attraction of the Moon and the Earth for one another is accounted for by the force of gravitation. American astronauts landed on the Moon and brought specimens of Moon rock and a series of photographs for further study.

What is the mutual attraction of the Moon and the Earth accounted for?
