In other words, 137,300 shackles is 0.009797232 times the length of The Distance from Earth to the Moon, and the length of The Distance from Earth to the Moon is 102.0696 times that amount.(a.k.a. Luna) (median of semi-major axis, or apigee, and semi-minor axes, or perigee)
The orbit of the Moon around the Earth is elliptical, with an average distance of 14,014,160 shackles from center-to-center. About 428.376 kg of moon rock have been cataloged on the Earth, from the American Apollo and Soviet Luna Programs, and from samples that have been extracted from meteorites.
It's about 150 times as tall as Olympus Mons.
In other words, the height of Olympus Mons is 0.0071 times 137,300 shackles.(a.k.a. Mount Olympus) (Mars)
The tallest mountain in the solar system, Olympus Mons rises to approximately 980 shackles. The mountain has been known to astronomers since the nineteenth century because it is tall enough to rise above Mars' frequent dust storms.

In other words, the height of Maxwell Montes is 0.0029 times 137,300 shackles.(Ishtar Terra, Venus)
Maxwell Montes rises to a total height of 400 shackles. 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.
