Olympus Mons (Latin for Mount Olympus) is a large volcanic mountain on the planet Mars. By one measure it has a height of nearly 22 km (14 mi); the tallest mountain on any planet in the Solar System, almost three times as tall as Mount Everest's height above sea level. Olympus Mons is the youngest of the large volcanoes on Mars, having formed during Mars's Amazonian Period. Olympus Mons had been known to astronomers since the late 19th century as...

Olympus Mons (Latin for Mount Olympus) is a large volcanic mountain on the planet Mars. By one measure it has a height of nearly 22 km (14 mi); the tallest mountain on any planet in the Solar System, almost three times as tall as Mount Everest's height above sea level. Olympus Mons is the youngest of the large volcanoes on Mars, having formed during Mars's Amazonian Period. Olympus Mons had been known to astronomers since the late 19th century as the albedo feature Nix Olympica (Latin for "Snows of Olympus"). Its mountainous nature was suspected well before space probes confirmed its identity as a mountain.
The volcano is located in Mars's western hemisphere at approximately 18°24′N 226°00′E / 18.4°N 226°E / 18.4; 226, just off the northwestern edge of the Tharsis bulge. The western portion of the volcano lies in the Amazonis quadrangle (MC-8) and the central and eastern portions in the adjoining Tharsis quadrangle (MC-9). Two impact craters on Olympus Mons have been assigned...
