Jan 18, 2016 at 21:12 comment added nigel222 Except that if a planet is large enough to hold an atmosphere, it is large enough to flow into the familiar oblate spheroid shape of Earth and the other planets under the ptessure caused by its own gravity. ISTR that's actually part of the definition of "planet".
