Despite doing a bit of internet research, I cannot seem to find out how to find the actual location of the vernal equinox. As I understand it, the equinox is the location that the equator crosses the celestial plane, and the location of the vernal equinox is the location on the equator that crosses the celestial plane. What is the best way to find that location?

  • $\begingroup$ There is almost nothing to "find" (as in no celestial object) at the vernal equinox. So what exactly are you looking for? Just the approximate position? $\endgroup$ – Raziman T V Jan 30 '17 at 16:47
  • $\begingroup$ Yes, I came across it reading an article on orbital mechanics related to ascending and descending nodes. $\endgroup$ – James Kirk Jan 30 '17 at 18:32

The answer is here. https://en.wikipedia.org/wiki/First_Point_of_Aries

There is also First Point of Libra.

  • $\begingroup$ Okay, so there actually is a constant location that you can look up at any given date? Thanks! $\endgroup$ – James Kirk Jan 30 '17 at 18:29
  • $\begingroup$ The position isn't constant. Due to precession (mainly) it moves, which is why the First Point of Aries is now in Pisces. $\endgroup$ – Dr Chuck Jan 30 '17 at 20:43
