By one measure , it has a height of nearly 25 km ( 13.6 mi or 72,000 ft ) . Olympus Mons is about two and a half times Mount Everest 's height above sea level . It is the largest volcano , the tallest planetary mountain , and the second tallest mountain in the Solar System compared to Rheasilvia on Vesta . It is the youngest of the large volcanoes on Mars , having formed during Mars 's Hesperian Period . It had been known to astronomers since the late 19th century as the albedo feature Nix Olympica ( Latin for `` Olympic Snow '' ) .
