The Largest Known Volcano

The largest volcano in our Solar System is on Mars. Olympus Mons is three times higher than Earth’s Mount Everest and sprawls over an area roughly the size of Poland. It’s an immense shield volcano, built long ago by fluid lava. Its last eruption is thought to have been about 25 million years ago
