What Astrological Aspects Are: How Conjunctions, Sextiles, Squares, Trines and Oppositions Read
Aspects are the angular relationships between two planets: the conjunction at 0°, the sextile at 60°, the square at 90°, the trine at 120° and the opposition at 180°. The closer the angle, the more noticeable the influence is usually thought to be, and since orbs differ from one line of practice to another, comparing two readings starts with checking that.
