Which planet has the tallest mountain in the solar system?

A Venus
B Earth
C Mars

Fact: Olympus Mons is a shield volcano that stands about 72,000 feet high, which is about 2.5 times the height of Mount Everest. It has a diameter of 373 miles—so large that an observer standing on its surface wouldn’t see its peak due to the planet’s curvature. Scientists believe it could still be dormant, with the last eruption occurring as recently as 25 million years ago.

Correct Answer: Mars
