WebRIGHT ASCENSION OF ASCENDING NODE, RAAN, The RAAN indicates the swivel or orientation of an orbit. It is the angle measured between the axis and the ascending node vector, or the vector pointing to the location where the satellite passes from the southern to northern hemisphere. The Sun appears to move northward during the northern spring, crossing 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.
