Are the mountains on the moon bigger than mount Everest?

The highest mountains in the world are in the Himalyas. Mount Everest is the tallest at over 29,000 feet, approximately 5-1/2 miles. The second highest is K2, also known as Mount Godwin Austen, at over 28,000 feet in height.

NotesThe above is the standard information regarding elevations above sea level. However, the Hawaiian volcano Mauna Kea 13,796 feet above sea level, is a volcanic mountain that rises 33,000 feet from base to summit. When measured this way, Mauna Kea is the tallest mountain in the world. Mauna Loa, with an elevation above sea level that is just a little under Mauna Kea, is also taller than Everest. Mauna Kea is the largest volcano in the world, with an estimated volume of 18,000 cubic miles.

The summit of Equador's Mount Chimborazo has the distinction of being the point farthest from the center of the earth at an elevation of 20,700 feet above sea level. This is because of the slight bulge in the planet around the equator. Chimborazo is about one degree south of the equator.

Away from Earth

There is a mountain, Mount Olympus Mons, in Mars that is 14 miles tall and is over 3 times taller than Mount Everest.
