Very nice. I guess the term I'm looking for for flatness of a theoretical sphere is equipotential.

An Idea. Not the planetary realities, on this one. Skewing toward the Idea scheme, what is the most round, most equipotential, "most flat" sphere in the large cosmos?

The largest, most remotely extragalactic, unspinning black hole?
The largest, most remotely extragalactic, unspinning red giant?

Yah, I'm aware that without tectonics, we'd be underwater. About three miles deep?

I don't know if orbital distance allows for water planets. Temp and atmos conditions favorable, without tectonic action. Seems the systems might have cooled too much by then, yada yada. I mean, since the concensus is (is it?) that earth's primary warmth is radioactive, not tidal. Well, with a little ray of sunshine. (That would be us.)

<<On an imperfect sphere, any flat area would be a "dimple". >>

Like a golf ball. They have dimples. No wonder I could never play the game, the balls were imperfect.
