Western aspects and chart patterns
What do trines and squares mean?
In Western astrology an aspect is the angle between two planets, measured round the chart. Each angle has a character. Because planets are rarely at an exact angle, an orb (a margin) is allowed: commonly about 8° for the major aspects (a little more when the Sun or Moon is involved) and 2–3° for the minor ones.
| Aspect | Angle | Character |
|---|---|---|
| Conjunction | 0° | Fusion: two forces act as one |
| Opposition | 180° | Tension and awareness: a tug of war seeking balance |
| Trine | 120° | Ease, natural talent, flow |
| Square | 90° | Friction that pushes you to act and grow |
| Sextile | 60° | Opportunity that rewards a little effort |
| Quincunx (inconjunct) | 150° | Awkward adjustment between unrelated needs |
| Semi-sextile | 30° | Mild, neighbourly link |
| Semi-square | 45° | Minor irritation |
| Sesquiquadrate | 135° | Minor stress that surfaces under pressure |
An aspect is applying when the faster planet is still moving towards the exact angle (the effect is building) and separating when it has passed (the effect is fading).
Aspect patterns
Grand TrineThree planets 120° apart, a triangle: natural gifts, sometimes too comfortable.
Grand CrossFour planets in two oppositions and four squares: great pressure and great drive.
T-squareAn opposition with a third planet square to both: the "apex" planet is where the tension is resolved.
YodTwo quincunxes from a sextile pair to one planet, the "finger of fate": a strong sense of mission.
KiteA grand trine with a fourth planet opposite one corner: talent given direction.
Mystic RectangleTwo oppositions joined by trines and sextiles: tension that can be handled well.
StelliumThree or more planets in one sign or house: a strong focus of life.
Chart shapes
The astrologer Marc Edmund Jones named seven overall shapes the planets can make round the wheel:
BundleAll within a third of the wheel: focused, specialised.
BowlAll within half: self-contained, with a mission.
BucketA bowl plus one "handle" planet that directs it.
LocomotiveSpread over two-thirds: driven, self-propelled.
SeesawTwo opposing groups: weighing choices.
SplayIrregular clusters: individualistic.
SplashSpread evenly: many interests.
