Human relationship of Earth's axial tilt (ε) to the tropical and polar circles

The Tropic of Cancer, which is also referred to as the Northern Tropic, is the nearly northerly circumvolve of latitude on World at which the Sun can be directly overhead. This occurs on the June solstice, when the Northern Hemisphere is tilted toward the Sun to its maximum extent.^[ane] It also reaches xc degrees beneath the horizon at solar midnight on the December Solstice. Using a continuously updated formula, the circle is currently 23°26′11.0″ (or 23.4364°) northward of the Equator.

Its Southern Hemisphere counterpart, marker the almost southerly position at which the Sun can be directly overhead, is the Tropic of Capricorn. These tropics are two of the five major circles of latitude that mark maps of Earth, the others being the Arctic and Antarctic circles and the Equator. The positions of these 2 circles of latitude (relative to the Equator) are dictated by the tilt of Globe's axis of rotation relative to the plane of its orbit, and since the tilt changes, the location of these 2 circles also changes.

In geopolitics, information technology is known for being the southern limitation on the mutual defence obligation of NATO, equally fellow member states of NATO are not obligated to come to the defence of territory below the Tropic of Cancer.

Name [edit]

When this line of latitude was named in the last centuries BC, the Sun was in the constellation Cancer (Latin for crab) at the June solstice, the fourth dimension each year that the Sun reaches its zenith at this breadth. Due to the precession of the equinoxes, this is no longer the case; today the Sunday is in Taurus at the June solstice. The word "tropic" itself comes from the Greek "trope (τροπή)", pregnant turn (modify of direction, or circumstances), inclination, referring to the fact that the Dominicus appears to "turn back" at the solstices.

Drift [edit]

Carretera 83 (Vía Corta) Zaragoza-Victoria, km 27+800. Of the Tropic of Cancer'southward intersections with Mexican federal highways, this is the only 1 where information technology is precisely marked and the drift from 2005 to 2010 can be seen.

The Tropic of Cancer'south position is non stock-still, but constantly changes because of a slight wobble in the World'southward longitudinal alignment relative to the ecliptic, the airplane in which the Earth orbits around the Lord's day. Earth's centric tilt varies over a 41,000-year period from 22.1 to 24.5 degrees, and equally of 2000^[update] is about 23.4 degrees, which will continue to remain valid for about a millennium. This wobble ways that the Tropic of Cancer is currently drifting south at a rate of nigh half an arcsecond (0.468″) of latitude, or 15 chiliad (49 ft), per year. The circle's position was at exactly 23° 27′N in 1917 and will be at 23° 26'Due north in 2045.^[two] The distance between the Antarctic Circle and the Tropic of Cancer is substantially abiding equally they motion in tandem. This is based on an assumption of a constant equator, but the precise location of the equator is not truly stock-still. Run across equator, centric tilt and circles of breadth for additional details.

Geography [edit]

North of the tropic are the subtropics and the North Temperate Zone. The equivalent line of breadth south of the Equator is chosen the Tropic of Capricorn, and the region between the two, centered on the Equator, is the tropics.

In the year 2000, more than half of the world's population lived due north of the Tropic of Cancer.^[3]

There are approximately 13 hours, 35 minutes of daylight during the summer solstice. During the winter solstice, there are 10 hours, 41 minutes of daylight.

Using 23°26'N for the Tropic of Cancer, the tropic passes through the following countries and territories starting at the prime meridian and heading eastward:

Climate [edit]

The climate at the Tropic of Cancer is generally hot and dry out, except for libation highland regions in China and easterly coastal areas, where orographic rainfall can be very heavy, in some places reaching 4 metres (160 in) annually. Most regions on the Tropic of Cancer experience two distinct seasons: an extremely hot summer with temperatures oftentimes reaching 45 °C (113 °F) and a warm winter with maxima around 22 °C (72 °F). Much land on or near the Tropic of Cancer is office of the Sahara Desert, while to the due east, the climate is torrid monsoonal with a brusque moisture season from June to September, and very little rainfall for the residue of the yr.

The highest mountain on or adjacent to the Tropic of Cancer is Yu Shan in Taiwan; though it had glaciers descending as depression as 2,800 metres (9,190 ft) during the Last Glacial Maximum, none survive and now no glaciers be within 470 kilometres (290 mi) of the Tropic of Cancer; the nearest currently surviving are the Minyong and Baishui in the Himalayas to the n and on Iztaccíhuatl to the due south.

Circumnavigation [edit]

According to the rules of the Fédération Aéronautique Internationale, for a flight to compete for a round-the-world speed record, it must encompass a distance no less than the length of the Tropic of Cancer, cross all meridians, and terminate on the same airfield where it started.

Length of the Tropic of Cancer at 23°26′eleven.7″Northward is 36,788 km (22,859 mi).^[4]

For an ordinary circumnavigation the rules are somewhat relaxed and the distance is set to a rounded value of at least 36,770 kilometres (22,850 mi).
