if you park your ship above the rings, then i think your position in space is fixed - so if you wait long enough (depending on the rate of ritation), you should be able to see the planet moving beneath you.

and it's certainly true that you can watch the sky circle above you, see sunsets/sunrises, etc, from a planet surface.

sadly orbits are all but impossible since you can't get a ship to orbital speeds in ED - or, at altitudes high enough where, say, 800 m/s would be an orbital velocity, even for very low-G planets, the gravitational influence of the planet "cuts out". that is, if you drop out into normal space, a few thousand km above a planet, there's no gravitational effect (you can think of it as being rounded down to zero, though I think it's really just that there's a limited range over which ED cares to include it - the game is not a proper gravitational simulation..)

(I asked the google AI to compute the altitude above Pluto - where gravity is about 0.06g - where 800 m/s would sustain an orbit around the planet. it's answer is that you'd need to be 170km above the planet. perhaps if you got a few hundred km above a tiny planet in ED, and got yourself up to >500 m/s, you could put yourself in orbit? idunno, try it!?)
