What Are Planetary Aspects?

Planetary aspects are the angles between planets in the sky. Picture a circle of 360 degrees: each planet’s position can be marked as a point on that circle, and an aspect is the distance in degrees between two of those points. Certain angles are considered meaningful in astrology, and each has its own name and character. Below are simple explanations of the five main aspects.

Conjunction

A conjunction is an angle of about 0 degrees, when two planets sit at almost the same point in the sky. Their influences blend and reinforce one another. Depending on the planets involved, a conjunction can feel like a strong, combined emphasis.

Opposition

An opposition is an angle of about 180 degrees, with the planets facing each other across the sky. It is often described as a tension between two opposite sides that need balancing, like the two pans of a scale.

Trine

A trine is an angle of about 120 degrees. It is traditionally seen as the most harmonious aspect: the energies of the planets combine easily and naturally, with little friction.

Square

A square is an angle of about 90 degrees. It is viewed as a tense aspect that creates inner friction or a push toward action. Many people read squares as challenges that prompt movement.

Sextile

A sextile is an angle of about 60 degrees. It is considered gently favorable: it opens opportunities, but it supports rather than pushes.

In practice, an aspect is rarely perfectly exact. The small allowance that is still counted is called the orb. To see which aspects are active in the sky right now, visit the current aspects page. It also helps to know the planet signs and the current moon phase.
