But should you allow the Earth to move, you can not only explain the day-to-day movement of The celebs, Moon, and Sunshine relative for the Earth’s sky by the Earth’s rotation, it is possible to describe the lunar and photo voltaic motions relative to the remainder of the sky as revolutionary orbits as a result of pressure of gravity.
Much like the Sunlight, the Moon follows a really identical route through the entire sky: it rises in direction of the East, sets in the West, and it does this — rises and sets — when every day. In addition it seems emigrate relative to The celebrities, completing an additional circle about as soon as each 29-to-thirty days.

That was just what exactly the Ptolemaic Product did, which sufficiently explained these motions with no detailing them.
