Newton's theory of "Universal Gravitation"

The Moon orbits around the Earth. Since its size does not appear to
change, its distance stays about the same, and hence its orbit must be
close to a circle. To keep the Moon moving in that circle--rather than
wandering off--the Earth must exert a pull on the Moon, and Newton
named that pulling force gravity.

The moon's eccentricity is a whopping 0.0549...

Newton's Law of Gravitation and Laws of motion... work
VERY well to predict the location of the moon in the Earth-Moon
system.
