太空船月球(国外英文资料) The average distance of the moon from the earth is about 380 thousand kilometers. The average distance of the sun from the earth is about 150 million kilometers. The 22 phase, we get the distance from the sun to earth is about 395 times the earth to the moon by far. The sun is about 1 million 380 thousand km in diameter, the diameter of about more than 3400 km, 22 division, the diameter is about 395 times bigger than the moon. The sun is 395 times the diameter of the moon, and the sun is 395 times farther from the earth. As the distance offsets the size, the two celestial bodies look larger than the earth, and their circle becomes the same! Look at the past from the ground, with roughly two large objects, a tube of a tube during the day, night, in the solar system, is not the same second cases. Famous scientist Asimov once said: from all kinds of data and rules to measure, the moon should not appear there.. He added: the moon is so big that it can cause an eclipse.

The problem is that such conditions are not what natural celestial bodies can do, then why? The planets of the solar system with satellite, it is a natural phenomenon, but our planet has a big unnatural satellite, the moon, that is to say as a satellite, and the volume of the moon than the earth is too big. Lets look at the following data: the earth is 12756 kilometers in diameter and the moon is 3467 kilometers in diameter. It is 27% of the earth. Mars is 6787 kilometers in diameter, with two satellite
