Equinox

Thursday 09/23/2010 7:26 AM

With day and night being about the same duration today, we witness the sun's passing of the celestial equator once again. In ancient times, this was called the First Point of Libra, because back then, the sun was just entering that constellation as summer ended. Times change and stars drift (see precession), so today we would probably name it The Second (or Third) Point of Virgo.

Round these parts, though, we just call it fall.
