The Largest Volcano In The Solar System Is On Mars: -Olympus Mons.

-Crazy Facts Of Cosmology.

Olympus Mons on Mars is 27 km tall almost 3 times the height of Mr. Everest and more than 2 time the height if Mauna Kea.

It is so tall that it essentially sticks of Mars's atmosphere.

Largest volcano in the solar system Olympus Mons and may have water in the past. Has the deepest valleys in the solar system. Has polar ice caps. Has two moons.

It is 550 km across at the base so wide that if you were standing at the edge of the caldera, the base of the volcano would be beyond the horizon.

Olympus Mons covers an area 300, 000 km^2 (120, 000 sq mi), roughly the same size as Italy.

Olympus Mons is the result of many thousands of basaltic lava flows. The extraordinary size of the volcano has been attributed to the lack of tectonic plate movement on the planet. The lack of movement allows the Martian crust to remain fixed in place over a magma hotspot allowing repeated, large lava flows. Many of these flows have levees along their edges.

Its height from base to peak is 21.9 km (13.6 mi or 72,000 ft) above the northern plains. This makes it at least two and a half times taller than Mt.  Everest's above sea level.
