The latitude of the Earth's equator is by definition 0Â° (zero degrees) of arc. The Equator is one of the five notable circles of latitude on Earth; the other four are the two Polar Circles: the Arctic Circle and the Antarctic Circle; and the two Tropical Circles: the Tropic of Cancer and the Tropic of Capricorn.
The equator is the circle where the Sun is directly overhead at noon on the equinoxes. The Arctic and Antarctic Circles are located at Â±66.5 degrees latitude. Note that 66.5 + 23.5 equals 90 degrees. This means that on December 21, when the Sun is directly over the Tropic of Capricorn at noon, it will not be visible from the Arctic Circle.
