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.
Annapurna I NepalSlide 2 of 21
Annapurna I Nepal
26,545 feet (8,091 meters)
The tenth highest mountain in the world, Annapurna I is located in western Nepal, while its smaller sister mountain Annapurna II is in the east. The name Annapurna translates to Goddess of the Harvests in Sanskrit, and is the name of a goddess of fertility and agriculture in Hinduism.
French mountaineers Maurice Herzog and Louis Lachenal were the first to reach Annapurna's summit in 1950, in the process becoming the first people in the world to climb a peak over 26,247 feet (8,000) meters. During the perilous journey, frostbite and gangrene forced the expedition doctor to perform emergency amputations, removing both of the explorers' toes and most of Herzog's fingers without anesthetic.Slide 3 of 21

Nanga Parbat Pakistan
26,657 feet (8,125 meters)
Nanga Parbat means "Naked Mountain" in Urdu and is also known by the name Diamir, or the "Dwelling Place of the Fairies." Its dangerous ice-covered terrain has also earned it the nickname "deadly mountain," as more than 60 mountain climbers have lost their lives attempting to scale the mountain, according to NASA.
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.Slide 5 of 21
Manaslu NepalSlide 6 of 21
26,781 feet (8,163 meters)
Located in the Mansiri Himal part of the Nepalese Himalayas, Manaslu translates to "Mountain of the Spirit" and is known for its beautiful valley glaciers and steep, snowy peaks. Prone to avalanches, glacier falls, monsoon rainfall and landslides, Manaslu's various scenic trekking routes are also treacherous.
Reaching the mountain's summit was not even attempted until the early 1950s, and the first climbers to successfully do so were the Japanese explorers Toshio Imanishi and Gyalzen Norbu, who mounted the summit in 1956.Slide 7 of 21
