In astrology, a square is a major aspect formed when two planets or other chart factors are approximately 90 degrees apart. It is traditionally associated with tension, friction, conflicting tendencies, challenge, and active adjustment between the factors involved. A square may point to areas where greater effort, awareness, or constructive response is needed. It is not inherently negative, and its meaning depends on the planets or points involved, their signs and houses, the size of the orb, and how the aspect fits within the larger chart pattern.
