An orb is the margin of error allowed around an exact aspect. If two points fall within the orb of an aspect, the aspect counts. Wider orbs catch weaker connections; tighter orbs keep only the strongest.
Per-point orbs used for aspects in a birth chart (degrees). This table covers every point — planets, nodes, Lilith, Chiron and Arabic Parts.
