What happens on the autumn equinox?
For most of the year, the Earth's axis is tilted either toward or away from the sun. That means the sun's warmth and light fall unequally on the northern and southern halves of the planet. During the equinox, the Earth's axis and its orbit line up so that both hemispheres get an equal amount of sunlight.
