My first ever up-close examination of Geologicals was in a quite spectacular place: a narrow sheer-sided canyon barely wide enough for the Asp to squeeze down into and find a landing spot. Needless to say, while I did land, I didn't dismiss the ship, because if it took off and landed again back up on top of the ridge, I'd never get up there.
My first Biologicals site was some rufous braintrees on this little moon, orbiting rather close to its parent planet. They offered some spectacular backdrops while fungi-farming. The brown dwarf the planet orbits can also be seen setting here.
And finally, another highly oblate molten ball of rock orbiting perilously close to a L-class brown dwarf, not entirely unlike Bomba's example on the previous page of this thread. To clarify: these worlds are not "egg-shaped", like a world would become IRL due to tidal stretching: ED doesn't model tidal stretching. Rather, these are the opposite of egg-shaped: "squashed-ball" shaped, because they're rotating so fast.
