The tropics are defined as the region between the Tropic of Cancer in the Northern Hemisphere at 23°26′09.7″ (or 23.43602°) N and the Tropic of Capricorn in the Southern Hemisphere at 23°26′09.7″ (or 23.43602°) S; [8] these latitudes correspond to the axial tilt of the Earth. The Tropic of Cancer is the Northernmost latitude from ...

While sidereal systems of astrology calculate twelve zodiac signs based on the observable sky and thus account for the apparent backwards movement of fixed stars of about 1 degree every 72 years from the perspective of the Earth due to the Earth's axial precession, tropical systems consider 0 degrees of Aries as always coinciding with the March ...
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 ...
(However, the tropical belt as defined based on atmospheric conditions is expanding due to global warming. [3]) The Earth's axial tilt has additional shorter-term variations due to nutation, of which the main term, with a period of 18.6 years, has an amplitude of 9.2″ (corresponding to almost 300 m north and south).

Two are named storms: Isaac and Joyce, and three will potentially develop into tropical depressions in the coming days. Isaac at one point was a Category 2 hurricane.
The Tropic of Capricorn's position is not fixed, but constantly changes because of a slight wobble in the Earth's longitudinal alignment relative to its orbit around the Sun. Earth's axial tilt varies over a 41,000 year period from about 22.1 to 24.5 degrees and currently resides at about 23.4 degrees. This wobble means that the Tropic of ...
