The height of summit above base of Olympus Mons has been measured by MOLA/NASA to be 21.9 km to the nearest 0.1 km. I'm aware of source references that give the height of Rheasilvia's central peak as 22 km, but this is only to the nearest 1 km. Where is the evidence that Rheasilvia's central peak is not actually between 21.5 and 21.9 km to the nearest 0.1 km, that is, actually lower than Olympus Mons? I think that until the height of Rheasilvia's central peak has been measured to the same degree of accuracy as Olympus Mons, accurate comparisions between the heights of these two mountains are suspect, unwise and invalid.

If new data becomes available in the future that changes current perceptions, we can change related articles. That's just part of building an Encyclopedia. -- Sleyece (talk) 23:41, 31 October 2018 (UTC)[reply]
