The Tropic of Cancer's position is not fixed, but constantly changes because of a slight wobble in the Earth's longitudinal alignment relative to the ecliptic, the plane in which the Earth orbits around the Sun. Earth's axial tilt varies over a 41,000-year period from about 22.1 to 24.5 degrees, and as of 2000 is about 23.4 degrees, which will ...

The Tropic of Cancer is the Northernmost latitude from which the Sun can ever be seen directly overhead, and the Tropic of Capricorn is the Southernmost. [8] This means that the tropical zone includes everywhere on Earth which is a subsolar point at least once during the solar year. Thus the maximum latitudes of the tropics have equal distances ...
The 23rd parallel north is a circle of latitude that is 23 degrees north of the Earth's equatorial plane, about 50 kilometres (31 mi) south of the Tropic of Cancer.It crosses Africa, Asia, the Indian Ocean, the Pacific Ocean, North America, the Caribbean, and the Atlantic Ocean.
Relationship between Earth's axial tilt (ε) to the tropical and polar circles. The polar circles would almost precisely match the boundaries for the zones where the polar night and the polar day would occur throughout the winter solstice and summer solstice day respectively.
By definition, the positions of the Tropic of Cancer, Tropic of Capricorn, Arctic Circle and Antarctic Circle all depend on the tilt of the Earth's axis relative to the plane of its orbit around the Sun (the "obliquity of the ecliptic"). If the Earth were "upright" (its axis at right angles to the orbital plane) there would be no Arctic ...
Relationship of Earth's axial tilt (ε) to the tropical and polar circles. The Arctic Circle is the southernmost latitude in the Northern Hemisphere at which the centre of the Sun can remain continuously above or below the horizon for twenty-four hours; as a result, at least once each year at any location within the Arctic Circle the centre of the Sun is visible at local midnight, and at least ...
The map of Juan de la Cosa is a world map that includes the earliest known representation of the New World and the first depiction of the equator and the Tropic of Cancer on a nautical chart. The map is attributed to the Castilian navigator and cartographer, Juan de la Cosa , and was likely created in 1500.
