oblateness

Newton's derivation of the precession from the gravitational action of the Moon and Sun raised three unresolved questions: What are the correct values for the mass of the Moon and the oblateness of the Earth?

If he looked carefully, he could just see that Saturn was not a perfect disk; on either side was something that no unaided human eye had ever seen before - the slight oblateness caused by the presence of the rings.

I had prepared a map of its track, in which an important error of the Berliner Jahrbuch (arising from neglect of the earth's oblateness) was corrected.

Applying the idea of centrifugal force to the earth considered as a rotating body, he perceived that it could not be a true sphere, and calculated its oblateness, obtaining 28 miles greater equatorial than polar diameter.
