The tallest mountain in the Solar System makes Everest look like a hill
Everyone knows Mount Everest, but it’s nothing compared to what’s out there in our own Solar System.
Meet Olympus Mons on Mars, the tallest known volcano and mountain we’ve discovered. It stands about 22 km (13.6 miles) high, which is nearly 3 times the height of Everest. But that’s not even the craziest part.
Olympus Mons is so massive that its base is about 600 km (370 miles) wide. That’s roughly the size of an entire country. If you were standing on its slopes, you probably wouldn’t even realize you were on a mountain, it rises so gradually that it feels like a slight incline.
Because Mars has lower gravity and no moving tectonic plates like Earth, the volcano just kept growing and growing over millions of years without collapsing or shifting.
It also has a giant caldera (collapsed crater) about 80 km wide.
