Tropic of Cancer

The Tropic of Cancer, or Northern tropic is one of the five major circles of latitude that mark maps of the Earth.

It is the parallel of latitude that lies currently 23 degrees 26′ 22″ north of the Equator.

It is the farthest northern latitude at which the sun can appear directly overhead, which occurs on the June solstice.

North of this line is the subtropics and Northern Temperate Zone.

The Tropic of Capricorn is at the opposite latitude south of the Equator.

South of the Tropic of Cancer and north of the Tropic of Capricorn are the Tropics.
