Orbs

Two planets are rarely at a perfectly exact angle. An orb is the margin of error you allow around the exact figure — the active zone within which an aspect still counts. It is not a hard wall but a sphere of influence: the closer two planets sit to exact, the more forcefully the contact shows up, in outer events and in inner life alike. As they drift apart, the link fades. Most astrologers put the working baseline somewhere between 5° and 10° — but which number, for which aspect, is exactly where they differ.

Why Astrologers Disagree on Orbs

Because an orb was never meant to be one fixed figure. It stretches and tightens with the situation, and four things move it. Read these as dials, not rules:

1. The aspect’s geometry — major aspects get more room than minor ones.
2. The planet’s magnitude — the Sun and Moon command a wide field; a small asteroid almost none.
3. Applying vs separating — a contact still forming counts for more than one already past.
4. The chart context — a private natal chart asks for tighter orbs than the meeting of two charts in synastry.

1. Aspect Geometry — Major vs Minor

The structural major aspects carry the chart’s biggest, most unavoidable themes, so they earn wide orbs. The finer minor aspects only register when tight — widen them and, mathematically, they begin to overlap and blur into the majors.

2. Planetary Magnitude — the Size of the Field

A bright, fast, heavy body throws a wider field than a faint one. The Sun and Moon get the most room; the personal planets a standard orb; the slow outer planets less, because their energy is deep but focused; tiny points least of all. The classical version of this exact idea is the moiety system, where each planet carries its own half-orb — see the moiety table for the rigorous traditional figures.

The two lights also have their own rules. The Moon, fastest body in the chart (about 13° a day), is given the widest orb of all when applying, since it crosses that distance in hours. The Sun works in the opposite direction up close: a planet drawn too near it is burned up — combustion — with a tiny core of cazimi where the burning flips into intensified strength.

3. Applying vs Separating — the Momentum

Identical orbs can mean opposite things depending on the direction of travel — and the faster planet always sets the rhythm.

An applying aspect is still moving toward exact: energy is gathering, potential turning into fact, and the orb is read generously. A separating aspect has already peaked and is dissolving; its influence fades, so the orb is read tight. Traditionally the applying contact is the stronger, future-leaning one. Which planet is doing the applying? The faster of the two — Venus moving toward Saturn, say, covers the degrees quickly and can hold a wider orb; a slow planet creeping toward exact must be read tight, or its “aspect” smears across years and loses all focus.

4. Chart Context — Natal vs Synastry, and Out-of-Sign

A natal chart is one person’s inner workings; hold its orbs to the disciplined standards above. In synastry and composite charts — two people meeting — the orbs widen (conjunctions out to ~10°), because here even a loose contact names a theme the relationship can’t ignore; the tighter the aspect, the more decisively it rules.

Context also overrides the signs. A planet at 29° Aries and another at 1° Taurus share no sign relationship at all — yet they sit only 2° apart. This is an out-of-sign (dissociate) aspect, and the math wins: a tight out-of-sign contact can hit as hard as any in-sign one. Beginners read the signs; the orb reads the geometry underneath them.

The Orb Matrix at a Glance

Put the four dials together and you get a working table. Treat the numbers as common ranges, not law — your own confirmation against real life is the final authority.

Two Lenses on the Same Number

An orb answers two questions at once, and you want both. Read classically, it measures strength and timing— how active a contact is right now, and, by applying or separating, whether its matter is still coming or already gone. Read psychologically, every aspect is a life-cycle, like the waxing and waning of the Moon, and the orb tells you where in that cycle you stand: the tighter the orb, the louder the knock at the door of growth. Hard aspects press you to face the work; soft ones let the potential flow. The degree is the same; the two readings simply look at it from the outside and the inside. Hold them together and an orb stops being a cut-off and becomes a reading in its own right.
