This Volcano on Mars is 3x Taller than Mount Everest!

There&a massive volcano on Mars, 3 times taller than Mount Everest. Olympus Mons is the Largest Volcano in the Solar System, measuring 25km tall and over 600km wide at the base. That is wider than the UK. It would take over 7 months to hike to the top. Although, you might want to hold your breath, Because Mars&atmosphere is so Thin, that the volcano&peak actually pokes out above it. Meaning if you were to hike Olympus Mons, you would have literally hiked into space! #space
