Tightest aspects
Figures in the chart
A list of aspects is not yet a reading. What your particular pairing means — where it helps and where it asks for attention — is what Luna reads from the whole chart, by voice.
Read my chartThe six aspects: what each one means
- ☌Conjunction · 0°
Two planets stand together and work as one force: the themes merge and amplify each other. It reads through the planets involved — Venus with Mars sounds nothing like Saturn with the Moon.
- ⚹Sextile · 60°
Gentle support: an opportunity that works when a step is taken toward it. Unlike a trine, a sextile does not run by itself — it waits for a small effort.
- □Square · 90°
Living tension as an engine: two themes pull in different directions, and that forces growth. Not a “bad aspect” but a task — usually the strongest part of a chart once a person learns to combine them.
- △Trine · 120°
Natural ease: what comes almost without effort, often so habitual it is not recognised as a talent. The only risk is leaving the gift unused because it is simply there.
- ☍Opposition · 180°
Two poles facing each other: work and home, freedom and closeness. It teaches balance instead of either-or — the maturity of this aspect is holding both.
- ⚻Quincunx · 150°
An awkward angle: the themes do not argue but do not fit either — like parts from two different sets. It demands constant adjustment and, in return, builds flexibility.
Figures: when aspects form a pattern
- △Grand trine
Three planets form an equilateral triangle: a closed circuit of ease within one element. It gives a steady talent but can lull — inside that triangle it is a little too comfortable.
- ⊤T-square
Two planets in opposition and a third squaring both — the apex of the figure. The apex shows what resolves the tension: it is the most workable point of the chart.
- ✚Grand cross
Four planets in a cross: two oppositions linked by squares. A lot of energy in four directions at once — a figure of endurance that unfolds closer to maturity.
Orbs: which ones we use and why
An aspect is rarely exact to the degree, so an orb is used — the tolerance within which the connection counts as active. Our values (the same as in the app):
- major aspects — 8° when the Sun or the Moon is involved, 6° otherwise;
- sextile — 5°, quincunx — 6°;
- auxiliary points (node, Lilith) — 3°, Chiron — 5°; two auxiliary points are not aspected to each other.
The smaller the orb, the stronger the aspect: a pairing with a 0.5° orb sounds far louder than the same pair at 5°. That is why the results are sorted by precision.
There are no “bad” aspects
Squares and oppositions are still called “malefic” — an outdated and harmful framing. A tense aspect supplies energy and forces a solution; professions and character usually grow out of exactly those places. Harmonious trines, by contrast, are easy to sleep through: a gift that came for free is rarely used to the full.
The practical rule is to look not at “good or bad” but at which two themes are linked and what to do about it. We hold that frame in the app as well.
Frequently asked questions
How many aspects should a chart have?
Usually 15–30 between planets, depending on the orbs a calculation uses. More or fewer does not mean better: what matters is which themes are linked and how exact the angles are.
What is an exact aspect?
One whose orb is close to zero: the planets sit at almost the perfect angle. Such pairings sound loudest in a chart, which is why our calculator lists them first.
Is a birth time needed for aspects?
For planet-to-planet aspects, barely: angles change little within a day and only the Moon moves noticeably. The time matters for houses and the ascendant.
Do you count aspects to Chiron and Lilith?
They are in the calculation with tighter orbs, but we do not show them on the site: it is professional jargon that confuses more than it helps without context. In the app Luna unpacks such points on request.
Calculating the angles is astronomy; interpreting them is a symbolic system for self-reflection, not science.
Aspects in the context of the whole chart
Luna reads aspects in context: sign, house, the strength of the planet — and translates it into plain language. Real ephemerides, a growth frame, no “fatal squares”.
