When two planets stand a precise angular distance apart on the ecliptic, they form an aspect — a conversation written in geometry across the 360° circle. Some of those conversations are fluid and reinforcing; others are charged, demanding, and ultimately the places where the most durable growth happens. Every aspect carries its own symbolic signature, shaped further by whether it is applying (the angle still tightening, the energy at its most potent) or separating (the angle widening, the energy integrating and waning). The orb — the allowable deviation from exactness — belongs not to the aspect itself but to the planets involved: the luminaries, Sun and Moon, command the widest orbs under the classical moiety system, while outer planets work within narrower bands.
Aspects
Conjunction
The conjunction unites two planets at 0° on the ecliptic, blending their energies into the most powerful aspect in astrology — its nature shaped entirely by the planets involved.
Opposition
The opposition is a 180° aspect that creates tension between two planetary forces, urging awareness, balance, and integration of opposing needs in the birth chart.
Trine
The trine is astrology's most harmonious major aspect — 120° of pure flow, innate talent, and ease that can quietly shade into complacency if left uncultivated.
Square
The square aspect — a 90° angle between two planets — is astrology's engine of friction and achievement, where tension becomes the raw material for real growth.
Sextile
The sextile is a 60° aspect linking two planets in harmonious tension — an open door that only rewards those who choose to walk through it.
Quincunx
The quincunx (150°) links two planets that share no common element or modality, demanding constant adjustment between energies that simply do not speak the same language.
Semi-Sextile
The semi-sextile is a 30° aspect linking adjacent zodiac signs, carrying mild friction and quiet growth potential that is easy to overlook in a chart.
Semi-square
The semi-square is a 45° minor hard aspect that produces subtle but persistent inner friction — a quiet pressure that demands attention and conscious effort.
Sesquiquadrate
The sesquiquadrate is a 135° minor hard aspect that builds persistent inner tension — a quiet pressure that demands adjustment, not crisis resolution.
