It's about one-fifteenth as tall as The Challenger Deep (Marianas Trench).
In other words, 779 meters is 0.071455 times the height of The Challenger Deep (Marianas Trench), and the height of The Challenger Deep (Marianas Trench) is 13.9950 times that amount.(near Marianas Islands, a.k.a. Ladrones Islands, northwestern Pacific Ocean) (depth below sea level)
The Challenger Deep, at the southern end of the Marianas Trench, reaches a depth of 10,902 meters below sea level. There has been only one manned expedition to the bottom of Challenger Deep — a 1960 voyage that took 4 hours and 48 minutes to reach the bottom.
It's about one-fifteenth as tall as Maxwell Montes.
In other words, the height of Maxwell Montes is 14 times 779 meters.(Ishtar Terra, Venus)
Maxwell Montes rises to a total height of 11,000 meters. 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.
