Mount Everest, at 29,029 feet tall (~5.5 miles), is the tallest mountain on earth (excluding Hawaii's Mauna Kea, which is actually 33,465 feet tall -- only 13,796 of which are above sea level). But it's got nothing on the tallest mountain in the solar system. Nope, Mars's Olympic Mons (not to be confused with mons pubic, the female vagina bone), takes the award at a staggering 27 miles tall. Pfft, I could hike it. I mean I never would because I'm lazy and hate even taking the stairs, but I could.
Olympus Mons is said to have reached such staggering heights the same way volcanoes form here on Earth -- minus one critical difference. Mars doesn't have plate tectonics. So instead of shifting over time to create a mountain range, Olympus Mons probably sat over a volcano-forming 'hot spot' for a really long time.
Oh you think you're sooooo special just because you have the tallest mountain in the solar system, do you, Mars? Too bad it looks like a rotting zombie nip! BURN -- earth's tits are way prettier!
