Tenzing Montes
Blocky mountain range on Pluto
From Wikipedia, the free encyclopedia
The Tenzing Montes /ˈtɛnzɪŋ ˈmɒntiːz/ (formerly Norgay Montes) are a range of icy mountains on Pluto,[4][5][6] bordering the southwest region of Sputnik Planitia and the nearby Hillary Montes and Wright Mons.[7][8] With peaks reaching 6.2 km (3.9 mi; 20,000 ft) in height, they are the highest mountain range on Pluto, and also the steepest, with a mean slope of 19.2 degrees.[4]

Naming
The mountains, first viewed by the New Horizons spacecraft on 14 July 2015, and announced by NASA on 15 July 2015, are named after the Nepalese mountaineer Tenzing Norgay, who, along with Sir Edmund Hillary, made the first successful ascent of the highest peak on Earth, Mount Everest (29 May 1953).[1][2][9] The mountains were informally called Norgay Montes by the New Horizons team, but that name was later changed from Norgay to Tenzing.[note 1] On 7 September 2017, the name Tenzing Montes was officially approved together with the names of Tombaugh Regio and twelve other nearby surface features.[10]
Highest peaks
Several massifs within Tenzing Montes reach elevations of more than 4 km above the surrounding terrain. The table below is based on Table 3 in.[4]
| Name of range | Peak name[note 2] | Location | Height (km, base-to-peak) |
|---|---|---|---|
| Tenzing Montes | "T2" | 16.4°S 175.6°E | 6.2±0.6 km |
| Tenzing Montes | "T1" | 16.0°S 174.9°E | 5.7±0.4 km |
| Tenzing Montes | "T3" | 16.9°S 176.3°E | 5.3±0.4 km |
| Tenzing Montes | "T4" | 21.7°S 179.7°E | 5.0±0.4 km |
| Tenzing Montes (south) | "T11" | 19.5°S 179.2°E | 4.5±0.4 km |
| Tenzing Montes (south) | "T12" | 20.3°S 178.9°E | 4.4±0.4 km |
The Tenzing Montes rise up to 6.2 km (3.9 mi; 20,000 ft) high, about twice as high as the Hillary Montes.[4] In comparison, Mount Everest rises 4.6 km (2.9 mi; 15,000 ft) base-to-peak (though to an elevation of 8.8 km (5.5 mi; 29,000 ft) above sea level).[11]
