Which latitude is defined as 23.5 degrees south of the equator?

The latitude defined as 23.5 degrees south of the equator is known as the Tropic of Capricorn. This specific latitude marks the southernmost point at which the sun can be directly overhead at noon, which occurs during the December solstice. It plays an important role in the Earth's climatic zones, as it delineates the boundary of the tropics in the southern hemisphere.

The Tropic of Cancer, located at 23.5 degrees north of the equator, represents the opposite boundary in the northern hemisphere. The Antarctic Circle, situated further south, defines the latitude beyond which there is at least one day of complete darkness in winter and one day of complete daylight in summer. The equator, on the other hand, is at 0 degrees latitude and serves as the baseline for measuring latitude north and south. Thus, the Tropic of Capricorn is distinctly recognized for its geographic significance at 23.5 degrees south.
