The mean distance from the Earth to the Moon 来自 EBSCO 喜欢 0 阅读量: 22 作者: J Meeus 摘要: The mean value (over time) of the distance between the centres of the Earth and the Moon is 385,000km, not 384,400km as given in many texts.This is based on the Moon's mean ...

How did the moon form? How long does it take the moon to orbit Earth? How far is the moon from Earth? We tackle all of these questions (and more) in our guide.
The meaning of MOON is the earth's natural satellite that shines by the sun's reflected light, revolves about the earth from west to east in about 291/2 days with reference to the sun or about 271/3 days with reference to the stars, and has a diameter of
The drag transfers energy from Earth to the moon, gradually expanding the latter’s orbit. The result is the slow expansion of lunar distance over time. As the lunar cycle increases, the Earth’s rotation will also slow down a tad. In a century, days will be longer by about two millisec...
How do we measure the distance between the Earth and the Moon? Over time, scientists have found new techniques to measure the distance from the moon to Earth. Each one is more accurate than the next. Find out more below. 1. Lunar Laser Ranging Experiments ...

The distance between the Earth and the moon grew as time passed. Currently, the moon drifts away from our planet at a rate of approximately 1.5 inches (3.8 cm) a year, roughly the same rate at which yourfingernails grow! Additional Resources ...
