The Aries Point

The Aries Point(AP)is actually not a single point nor is it only in Aries. This term refers to any planet found at 0 degrees in any of the cardinal signs (Aries, Cancer, Libra and Capricorn).

For example:
Mercury at 0 Capricorn, we say that Mercury conjuncts to the Aries Point(AP)
Mercury at 0 Cancer = Mercury conjunct AP
Pluto at 0 Libra = Pluto conjunct AP
Sun at 0 Aries = Sun conjunct AP

Mercury conjunt AP here (along with P. of fortune but thats not a planet)

My Son has Uranus conjunt AP.
