嫦娥奔月是我国古代美丽的神话故事,但一直到最近几十年,人类才真正使“嫦娥”奔上月球。正是牛顿三大运动定律的推出和地球引力的发现,使得这一切成为可能。万有引力定律揭示了天体运动的规律,为实际的天文观测提供了一套计算方法。利用它可以只凭少数观 The moon and the moon are the beautiful ancient myths in our country. However, until recently, human beings really made the moon Chang’e go to the moon. It is exactly the introduction of the three Newtonian laws of motion and the discovery of the gravitation of the earth that makes all this possible. The law of universal gravitation reveals the law of celestial movement and provides a set of calculation methods for actual astronomical observations. Use it only by a few observations
