Mount Everest, also known in Nepal as Sagarmatha and in Tibet as Chomolungma, is Earth's highest mountain. It is located in the Mahalangur mountain range in Nepal and Tibet. Its peak is above sea level. It is not the furthest summit from the centre of the Earth. That honour goes to Mount Chimborazo, in the Andes. The international border between China (Tibet Autonomous Region) and Nepal runs across Everest's precise summit point. Its massif includes neighbouring peaks Lhotse, ; Nuptse, and Changtse, .
