The largest relief measured on any body in the Solar System, meters.
Vesta's Rheasilvia central peak is ~22 km on a 262 km body; Olympus Mons is 21.9 km on one 3,390 km across. Four orders of magnitude of surface gravity between them and the same number, which is the empirical fact this constant is: relief saturates, and it saturates at about twenty-two kilometers.
