The Tropic of Cancer is located at 23°30' N and is the northern
boundary of the tropics. The Tropic of Capricorn is located at
23°30' S, and is the southern boundary of the tropics. They mark the
farthest point north or south at which the sun can be seen directly overhead
at noon. The Arctic Circle is
located at 66 1/2°N and marks the northernmost point at which the
sun can be seen at the winter solstice (about Dec. 21) and the southernmost
point of the northern polar regions at which the midnight sun is visible.
