Astrology Transits Explained: Aspects, Orbs and Timing

What are transits in astrology?

A natal chart is calculated for one birth moment, while a transit chart shows planetary positions for another date and time. Reading transits places the moving chart around the natal chart and looks for angular relationships between them. The astronomical positions can be calculated; their personal meaning is an astrological interpretation.

The four-part transit formula

1. Transiting planet: the function currently moving.
2. Natal planet or angle: the chart factor being contacted.
3. Aspect: the geometric relationship between them.
4. House: the life area where the transit occurs.

Conjunctions, oppositions, squares, trines and sextiles

A conjunction joins two factors at approximately the same degree. An opposition links positions about 180 degrees apart, a square 90 degrees, a trine 120 degrees and a sextile 60 degrees. Astrologers often read conjunctions as concentrated, squares and oppositions as tension, and trines and sextiles as easier flow. Easy does not always mean useful, and difficult does not mean disastrous.

What is a transit orb?

An orb is the permitted distance from an exact aspect. Faster transits are often read with narrower time windows, while slow outer-planet contacts may be followed over months. There is no universal orb for every technique. Choose a consistent limit and distinguish an applying aspect, exact contact and separating aspect.

Fast planets versus slow planets

The Moon, Sun, Mercury, Venus and Mars move through contacts relatively quickly and may describe short-lived moods, attention or activity in an astrological reading. Jupiter through Pluto move more slowly, so their transits can frame longer periods. Duration alone does not make a transit more important than lived circumstances.

Transiting planets through natal houses

A planet's transit through a house is interpreted through that house's topics even when it forms no exact aspect. Accurate house timing depends on reliable birth time and the chosen house system. If the birth time is unknown, prioritize planet-to-planet aspects and clearly mark house claims as uncertain.

Why one transit may become exact several times

Apparent retrograde motion can carry a planet across the same natal degree on a direct pass, a retrograde pass and a final direct pass. Astrologers may interpret these as an introduction, review and integration, but the sequence does not require three matching external events.

What is a planetary return?

A return is a conjunction between a transiting planet and its own natal position. The Jupiter return occurs about every twelve years, while the Saturn return occurs about every twenty-nine years. Returns are one category of transit rather than a separate chart system.

How to prioritize multiple transits

Start with slow, close contacts to the Sun, Moon, Ascendant, Midheaven and personal planets. Then note repeated themes across houses, rulers and faster triggers. Avoid giving ten unrelated predictions. A few coherent patterns are more useful than treating every minor aspect as equally decisive.

How to read your current transits

1. Use accurate natal data and select a target date.
2. List the closest major aspects first.
3. Name the moving and natal planets.
4. Add the natal house and transited house when time is reliable.
5. Check stations and repeated contacts.
6. Compare the symbolism with current facts, choices and priorities.

What transits cannot predict reliably

Transits cannot reliably promise marriage, pregnancy, death, illness, financial gain, a breakup or an exact external event. Similar transits occur for many people whose circumstances differ. Use them as reflective timing prompts, never as a substitute for medical, legal, financial or safety guidance.
