At the North Pole and South Pole, the solstices mark the time when the sun is highest or lowest in the sky. The Sun's declination varies with the seasons. It reverts to zero declination when fall equinox comes and drops to the negative 23.5 declination during the winter solstice. This December solstice is called the winter solstice in the northern hemisphere, whereas in the southern, it is the summer solstice. The following equation gives a more accurate value of the declination angle. (An ellipsoid is an approximation to sea level that is mathematically manageable). Because of the tilt of the Earth, on the day of the summer solstice the Sun appears 23.45 degrees higher in the sky than it would if the Earth did not spin on a tilt, and on the day of the winter solstice the Sun appears 23.45 degrees lower in the sky than it would if the Earth did not spin on a tilt. Thus, we can conclude, the maximum value of the solar declination angle is 23.44, and the minimum is 23.44. On our planet, solstices are defined by solar declinationthe latitude of the Earth where the sun is directly overhead at noon. The declination reaches a maximum of 23.45 on June 22 (summer solstice in the northern hemisphere) and a minimum of -23.45 on December 21-22 (winter solstice in the northern hemisphere).
