The celestial equator and ecliptic coincide at two locations, known as the vernal equinox and autumnal equinox, where the Sun appears to cross the celestial equator during the equinoxes. The celestial equator is the projection of the Earth's equator onto the celestial sphere, while the ecliptic is the path that the Sun appears to follow through the sky over the course of a year. These two circles intersect at two points on the celestial sphere called the vernal equinox and autumnal equinox.
