Mars - Olympus MonsYour model is disabled. For more details go to Edit properties3D Model
Olympus Mons is a very large shield volcano on the planet Mars. The volcano has a height of nearly 25 km. 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. Its mountainous nature was suspected well before space probes confirmed its identity as a mountain.
