Olympus Mons on Mars


We are not able to observe mountains beyond our own solar system yet. So the current record holder is Olympus Mons on Mars at about #3# times the height of Mount Everest.

NOT Olympus Mons


According to http://study.com/academy/lesson/olympus-mons-facts-height-quiz.html, Olympus Mons - 22 km (13.7 mi) is the second highest mountain in the universe, and I am trying to find out what mountain is higher...

Rheasilvia Mons, 4 Vesta Asteroid – 23 km (14.2 mi)
4 Vesta Asteroid is orbiting our sun.
