What is the name for the point on the ecliptic when the sun is at its greatest distance from the equator?
Position of the Sun is directed toward the north celestial pole ), in astronomical units: Where the obliquity of the ecliptic is not obtained elsewhere, it can be approximated: for use with the above equations. The Sun appears to move northward during the northern spring, contacting the celestial equator on the March equinox. Its declination reaches a maximum equal to the angle of Earth's axial tilt (23.44°) on the June solstice, then decreases until reaching its minimum (−23.44°) on the December solstice, when its value is the negative of the axial tilt. This variation produces the seasons. A line graph of the Sun's declination
Ecliptic the equator is projected outward to the celestial sphere, forming the celestial equator, it crosses the ecliptic at two points known as the equinoxes. The Sun, in its apparent motion along the ecliptic, crosses the celestial equator at these points, one from south to north, the other from north to south. The crossing from south to north is known as the vernal equinox, also known as the "first point of Aries" and the "ascending node of the ecliptic" on the celestial equator. The crossing from north to south is the autumnal equinox or descending node. The orientation of Earth's axis
