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 currently (Epoch 2010) lies 23º 26′ 17″ south of the equator[1]

It is drifting north at the rate of almost half a second (0.47) of latitude per year (it was at exactly 23º 27' S in year 1917).[2]

For checking and/or calculating these and other astronomical "constants", see below under External links.

It 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.

Geography

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

Starting at the Prime Meridian and heading eastwards, the Tropic of Capricorn passes through:

Name

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.

Cultural significance

In India, the day of sun entering the zodiacal belt Capricorn is celebrated as Makara Sankranti festival. Tropic of Capricorn is called Makara Vrutta in Indian languages.
