The parallel of latitude approximately 23½°(23.45°)south of the Equator. It was named for the constellation Capricornus (the goat), for astronomical reasons which no longer prevail.

Because the Earth, in its revolution around the Sun, has its axis inclined 23½° from the vertical to the plane of the ecliptic, the Tropic of Capricorn marks the southern limit of the zenithal position of the Sun. Thus, on December 22 (Southern Hemisphere summer, but northern winter solstice) the Sun, at noon, is 90° above the horizon.

The Tropic of Capricorn is the southern boundary of the equatorial zone referred to as the tropics, which lies between the Tropic of Capricorn and the Tropic of Cancer. See also Mathematical geography; Solstice; Tropic of Cancer.

Tropic of Capricorn, parallel of latitude at 23°30′ south of the equator; it is the southern boundary of the tropics. This parallel marks the farthest point south at which the sun can be seen directly overhead at noon; south of the parallel the sun appears less than 90° from the northern horizon at any day of the year. The sun reaches its vertical position over the Tropic of Capricorn at about Dec. 22, the summer solstice for the Southern Hemisphere. The term Capricorn comes from the Latin words caper [goat] and cornu [horn] and is the name given to one of the 12 constellations in the zodiac.

World map showing the Tropic of Capricorn

The Tropic of Capricorn, or Southern tropic, is one of the five major circles of latitude that mark maps of the Earth. It lies 23° 26′ 22″ south of the equator, and marks the most southerly latitude at which the sun can appear directly overhead at noon. This event occurs at the December solstice, when the southern hemisphere is tilted towards the sun to its maximum extent.

The northern hemisphere equivalent of the Tropic of Capricorn is the Tropic of Cancer. Latitudes south of the Tropic of Capricorn are in the Southern Temperate Zone. The region north of the Tropic of Capricorn and south of the Tropic of Cancer is known as the tropics.

The Tropic of Capricorn is so named because about 2,000 years ago the sun was entering the constellation Capricornus (capricorn is Latin for goat horn) at the December solstice. In modern times the sun appears in the constellation Sagittarius during this time. The change is due to precession of the equinoxes. The word "tropic" itself comes from the Greek tropos, meaning turn, referring to the fact that the sun appears to "turn back" at the solstices.

The position of the Tropic of Capricorn is not fixed, but varies in a complex manner over time; see under circles of latitude for information.
