Scientists are now able to pinpoint exactly how tall every mountain on Earth is, thanks to NASA's use of the Earth Observing System series of satellites.

Measuring each mountain's summit, or tallest point, by their height above sea level, the 10 tallest mountains in the world all turn out be located in the Himalayas. Each of these mountains belongs to the "eight-thousanders" club, a list that consists of the 14 mountains on Earth that are 8,000 meters (about 26,250 feet) tall or more.

Meet the "eight-thousanders" and the brutal challenges they pose to the people who try to climb them.

Climbing Nanga Parbat is in fact so dangerous that while over 1,800 people have reached Everest's summit, only about 216 people have successfully gotten to the top of Nanga Parbat.
