Due to the precession of the earth, in which constellation will the vernal equinox occupy next?
March equinox signals the beginning of spring in the Northern Hemisphere and autumn in the Southern Hemisphere. It marks that special moment when the sun crosses the celestial equator going from south to north. It can come on March 19, 20 or 21. In 2016, it will come on March 20 (in fact this is true for next 3-4 decades), when it will be in Pisces constellation.
