Tristan da Cunha,
colloquially Tristan, is the name of both a remote group of volcanic
islands in the south Atlantic Ocean and the main island of that group.
It is the most remote inhabited archipelago in the world, lying 2,000
kilometres from the nearest inhabited land, Saint Helena, and
2,400 kilometres from the nearest continental land, South
Africa. It is 3,360 kilometres from South America.
The territory consists of the main island, named Tristan da Cunha,
which has a north–south length of 11.27 kilometres and an
area of 98 square kilometres, along with the smaller, uninhabited
Nightingale Islands and the wildlife reserves of Inaccessible and Gough
islands. As of January 2017, the main island has 262 permanent
inhabitants. Meanwhile, the other islands are uninhabited, except for
the personnel of a weather station on Gough Island. Tristan
da Cunha is part of the British overseas territory of Saint Helena,
Ascension and Tristan da Cunha. This includes Saint Helena and
equatorial Ascension Island, some 3,730 kilometres to the
north of Tristan.
