Could a planet-sized object be donut shaped? From the definition of the planet, it's:
-is in orbit around the Sun,
-has sufficient mass so that it assumes a hydrostatic equilibrium (nearly round) shape, and
-has "cleared the neighbourhood" around its orbit
If there however was a way for donut-shaped planet to exist, would it be able to hold atmosphere?
