The Semi-Sextile is a geometric aspect between two planets that are approximately 30° apart. It indicates either an annoying or mildly pleasant relationship between the planetary energies.

When two planets are 45° degrees apart (give or take a few degrees of orb) they are in a Semisquare aspect (sometimes called an Octile). Its effect is irritating and annoying but can also be motivating.

When two planets are 135° degrees apart (give or take a few degrees of orb) they are in a Sesquiquadrate aspect (sometimes called a Tri-Octile). Its effect is irritating, annoying and sometimes triggers anxiety, but can also be motivating.

The Sextile is an aspect between two planets that are 60 degrees apart (give or take a few degrees of orb). The aspect is typically creative, easy-flowing and often indicates natural ability.

The Square Aspect joins planets that are 90 degrees apart (give or take a few degrees of orb). This aspect typically indicates stress and conflict, but can also be motivating and dynamic.
