question why does the moon move around the earth why it doesnt hit the earth under the effect of gravity??
The prevailing theory is that the Moon was created when a collision occurred between Earth and another body. This sent much of protoEarth flying in a spray of rubble. The fate of the rubble can be classified into three categories:but why did the moon have orbital speed in the first place
It requires no energy to stay in orbit.and how does it have the same energy to continue with same speed (this question about satellite and other planets too).
