When two planets are 90 degrees apart, they are in square. This aspect can create tension and challenges, but it can also be a source of motivation and growth.

Squares usually occur between planets in signs of the same modality (cardinal, fixed, mutable). For example, Aries and Capricorn, or Taurus and Leo.

Sun square Moon can create inner conflict and challenges in finding emotional balance and may require more effort to be addressed.

Mars square Venus can create tension in relationships and may require more effort to find balance between passion and harmony.
