Tropic of Capricorn

The Tropic of Capricorn (pronunciation: /ˈtrɒpɪk əv ˈkæp.rɪ.kɔːrn/) is one of the five major circles of latitude that mark maps of the Earth. It is the southernmost point on Earth where the Sun can be directly overhead at noon. This event occurs once per year, at the December solstice, when the Southern Hemisphere is tilted towards the Sun to its maximum extent.

Etymology

The term "Tropic of Capricorn" is derived from the constellation of Capricornus (Latin for "horned goat"), which is located in the southern hemisphere. The word "tropic" comes from the Greek "tropos" meaning "turn", referring to the fact that the Sun appears to "turn back" at the solstices.
