Tropic of Cancer

The Tropic of Cancer lies 23° 26' 22" (23.4394°) north of the Equator and marks the most northerly latitude at which the sun can appear directly overhead at noon. This event occurs at the June solstice, when the northern hemisphere is tilted towards the sun to its maximum extent. The Earth's tropical zone ("the tropics") includes everything between the Tropic of Cancer and the Tropic of Capricorn.
