Most planets aren't even spherical in the same way that a piece of paper isn't even flat.

A fun read about this:

- [Asimov - The Relativity of Wrong](http://chem.tufts.edu/answersinscience/relativityofwrong.htm)

From the link above:

> To put it another way, on a flat surface, curvature is 0 per mile everywhere. On the earth's spherical surface, curvature is 0.000126 per mile everywhere (or 8 inches per mile). On the earth's oblate spheroidal surface, the curvature varies from 7.973 inches to the mile to 8.027 inches to the mile.

> The correction in going from spherical to oblate spheroidal is much smaller than going from flat to spherical. Therefore, although the notion of the earth as a sphere is wrong, strictly speaking, it is not as wrong as the notion of the earth as flat.

You're being unnecessarily pedantic. There's a clear difference between oblately spherical and lumpy.

You seem to read my comment as contradicting rather than supplementing.

Sorry, your use of "even" made it seem like you were trying to be contradictory.

Perhaps you meant, "No planets are perfectly spherical"?
