...bodies in the solar system, and probably every other body in the whole compass of space. This law, viz. that the squares of the periodic times of the planets...other as the cubes of their mean distances from the central body, was first discovered by Kepler, and afterwards demonstrated by Sir Isaac Newton. Thus,... | |
