The highest mountain on Mars is also the highest mountain and volcano in the entire solar system. It is called Olympus Mons and is 16 miles (24 kilometers) high which makes it about three times higher than Mt. Everest. In addition to being very tall, it is also very wide (340 miles or 550 kilometers) and covers an area larger than the entire chain of Hawaiian islands.
Olympus Mons. At a height of 25km, Olympus Mons on Mars is the largest volcano in the Solar System and is nearly three times as tall as Mount Everest. It is thought that one of the reasons that Olympus Mons and the other volcanoes on Mars are large is that the Red Planet's crust doesn't move like the Earth's. This lack of active plate tectonics means that rising magma erupted on the same part of the planet's crust and slowly built up a very large volcano. Eruptions of Olympus Mons and the other volcanoes on Mars are thought to have ceased due to the cooling of Mars's core.
