The Full Story

The largest volcano in the Solar System is Olympus Mons, located on Mars. It is a shield volcano with broad, gently sloping sides, formed by repeated lava flows over a long period. At about 22 km tall and roughly 600 km wide, it is far larger than any volcano on Earth. Its size reflects Mars’s low gravity and the lack of plate tectonics, which let lava build up in one place for a very long time.
