It's about one-fortieth as tall as Olympus Mons.
In other words, the height of Olympus Mons is 42 times 868 paces.(a.k.a. Mount Olympus) (Mars)
The tallest mountain in the solar system, Olympus Mons rises to approximately 35,000 paces. The mountain has been known to astronomers since the nineteenth century because it is tall enough to rise above Mars' frequent dust storms.
It's about one-fifteenth as tall as Maxwell Montes.
In other words, the height of Maxwell Montes is 17 times 868 paces.(Ishtar Terra, Venus)
Maxwell Montes rises to a total height of 14,000 paces. Since Venus does not seem to have the kind of tectonic activity which gives rise to mountains on Earth, the origin of the Venusian mountain remains the subject of some dispute.
