Saint Helena Saint Helena (/ˌseɪnt həˈliːnə/ SAYNT-hə-LEE-nə) is a volcanic tropical island in the South Atlantic Ocean, 4,000 kilometres (2,500 mi) east of Rio de Janeiro and 1,950 kilometres (1,210 mi) west of the Cunene River, which marks the border between Namibia and Angola in southwestern Africa. It is part of the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha.[3] Saint Helena measures about 16 by 8 kilometres (10 by 5 mi) and has a population of 4,534 (2016 census).[2] It was named after Saint Helena of Constantinople.
Null Island Null Island is a name for the area around the point where the prime meridian and the equator cross; in the WGS84 datum, this is at zero degrees latitude and longitude [0°N 0°E﻿ / ﻿0°N 0°E﻿ / 0; 0.[1]] (the location is in the Gulf of Guinea off the west African coast). The name 'Null Island' serves as both a joke based around the suppositional existence of an island there (in reality, only a buoy [pictured] exists there), and also as a name to which coordinates erroneously set to 0,0 are assigned in placenames databases in order to more easily find and fix them. The nearest land is Annobón island, at 1°25′S 5°38′E﻿ / ﻿1.417°S 5.633°E﻿ / -1.417; 5.633.
