Only at the spring and fall equinoxes is the declination angle equal to 0. At the poles, a solstice is the peak of a radical exposure to daylight, while at the Equator, the solstices are barely marked at all. On these days, the earths axis of rotation becomes perpendicular to the rays of the sun. The Arctic and Antarctic circles today are 1.2 m (4 ft) closer to the poles, and the Tropic of Cancer and Tropic of Capricorn are equally closer to the equator . At the North Pole and South Pole, the solstices mark the time when the sun is highest or lowest in the sky. The solar declination varies from -23.44 at the (northern hemisphere) winter solstice, through 0 at the vernal equinox, to +23.44 at the summer solstice.

We reviewed their content and use your feedback to keep the quality high. Since the Earth is tilted on its axis and rotates every year, the angle of declination changes throughout the year. The subsolar point then begins its migration south, and vertical rays strike the Tropic of Capricorn, 23.5 south of the Equator, during the December solstice. are also often used in the literature. As a result, areas near Earths Equator experience relatively constant sunlight and little solstice variation. For a listing of Declinations (non-graphical) see the Declinations Ephemeris page.
