Square

Definition

The square is a major aspect formed when two planets are separated by 90°, creating a disharmonious connection. It is associated with conflict, obstacles, and growth through effort. The tension arises because planets in square are typically in signs of incompatible modalities or elements, forcing a resolution of competing needs or goals. Squares highlight areas of life where growth requires persistence and where integration of differing perspectives is essential. While challenging, they are also catalysts for progress, as they demand action and problem-solving. A square can involve personal planets, outer planets, or a combination, each bringing its own flavor of friction.

In a chart

In a natal chart, a square appears when two planets are separated by exactly 90° (with an orb of up to 8°). Look for planets in signs of the same modality (Cardinal, Fixed, or Mutable) but differing elements, such as Aries and Cancer. Ignore any near-90° angles that exceed the standard orb. Squares often form part of larger aspect patterns, like T-squares or Grand Crosses.

Examples

• Mars in Aries square Moon in Cancer
• Venus in Capricorn square Uranus in Aries

History

The concept of the square originates from ancient Hellenistic astrology, where aspects were based on geometric divisions of the zodiac. Ptolemy formalized it in the 2nd century CE.
