Astrological aspect
Aspects compare positions through angles of ecliptic longitude. Conjunction, sextile, square, trine and opposition correspond to 0°, 60°, 90°, 120° and 180°.
How it is defined
The orb is the tolerance around the exact angle. Measure the smaller separation around the circle, correcting the difference when it crosses 0°.
How to read it
Start by identifying the factor, its position and the data behind it. Then explore its symbolic reading and consider which questions make sense in your own experience.
A concrete example
The separation between 350° and 10° is 20°, not 340°. Interpretation then requires an orb criterion; geometry alone does not determine an event.
