The meridian 20° east of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, Europe, Africa, the Atlantic and Indian oceans, the Southern Ocean, and Antarctica to the South Pole.
Part of Namibia's borders with Botswana and South Africa are defined by the meridian. The boundary between the Atlantic Ocean and the Indian Ocean is defined by the meridian. The meridian defines the eastern limit of the New Swabia area in Queen Maud Land, Antarctica.

Part of Namibia's border with Botswana is defined by the meridian.50th parallel north
The 50th parallel north is a circle of latitude that is 50 degrees north of the Earth's equatorial plane. It crosses Europe, Asia, the Pacific Ocean, North America, and the Atlantic Ocean.
At this latitude the sun is visible for 16 hours, 22 minutes during the summer solstice and 8 hours, 4 minutes during the winter solstice.
The maximum altitude of the sun on the summer solstice is 63.5 degrees and on the winter solstice it is 16.5 degrees.At this latitude, the average sea surface temperature between 1982 and 2011 was about 8.5°C (47.3°F).Botswana–South Africa border
The border between Botswana and South Africa is 1,969 kilometres (1,223 mi) long. More than 90% of the border follows rivers, including the Nossob, Molopo, Marico and Limpopo.Namibia–South Africa border
The border between Namibia and South Africa is 967 kilometres (601 mi) long. It runs along the Orange River from its mouth on the Atlantic Ocean to the 20th meridian east, and then northwards along that meridian to the tripoint with Botswana at the Nossob River.
