Mount Everest (Tibetan: ཇོ་མོ་གླང་མ, Wylie: jo mo glang ma;Chomolungma or Qomolangma choh-moh-lahng-mə,"Holy Mother"; Chinese: 珠穆朗玛峰; pinyin: Zhūmùlǎngmǎ Fēng; Nepali:सगरमाथा, Sagarmāthā is the Earth's highest mountain, with a peak at 8,848 metres (29,029 ft) above sea level. It is located in the Mahalangur section of theHimalayas. The international border between China and Nepal runs across the precise summit point.[citation needed] Its massif includes neighboring peaks Lhotse, 8,516 m (27,940 ft); Nuptse, 7,855 m (25,771 ft); and Changtse, 7,580 m (24,870 ft).
In 1856, the Great Trigonometric Survey of British India established the first published height of Everest, then known as Peak XV, at 29,002 ft (8,840 m). In 1865, Everest was given its official English name by the Royal Geographical Society upon a recommendation by Andrew Waugh, the British Surveyor General of India. Waugh named the mountain after his predecessor in the post, Sir George Everest. Although Tibetans had called Everest "Chomolungma" for centuries, Waugh was unaware of this because Nepal and Tibet were closed to foreigners.
The highest mountain on the Earth attracts many well-experienced mountaineers as well as capable climbers willing to hire professional guides. While not posing substantial technical climbing challenges on the standard route, Everest presents dangers such as altitude sickness, weather and wind.
