The conjunction
Two drives, one voice.
0° · orb 8° · 10° with the Sun or Moon
Mix two paints in one can and no amount of stirring gets them back out again. That’s a conjunction: two planets standing so close together on the wheel that the chart stops treating them as two planets.
What a conjunction is
A conjunction puts two planets at the same degree — an angle of zero, no distance across which to disagree. It’s the only major aspect where the pair almost always shares a sign, so both planets work in the same style while sharing one microphone. Venus conjunct Mars is the textbook case — attraction and pursuit fused into a single gesture, people for whom the compliment is also the opening move.
In the birth chart calculator a conjunction is counted when two bodies sit within 8 degrees of each other — 10 degrees when the Sun or Moon is involved. Only the opposition gets the same slack; fusion, like confrontation, is hard to miss. Minor aspects exist too — the semi-sextile, the quincunx, and their relatives — but the calculator counts the five majors and stops there; the minors add noise faster than they add signal.
Living inside a fusion
From the inside, a conjunction doesn’t feel like an aspect. It feels like your personality. There’s no gap between the two drives, so there’s no vantage point from which to watch them operate — other people usually spot the blend long before you do. Moon conjunct Saturn produces feelings that arrive pre-checked for practicality; Sun conjunct Mercury fuses identity with speech, so what you say is, inconveniently, who you are.
The conjunction has no character of its own until you name the planets: Moon–Mars reads as a hair trigger, Venus–Saturn as affection with a vetting process. Same geometry, entirely different weather.
Getting the blend right
The work of a conjunction is differentiation — learning to tell which planet is talking. A Venus–Mars person who assumes all of it is Venus will keep wondering why their friendliness starts fires. Naming the second ingredient doesn’t unmix the paint, but it does tell you what you’re painting with.
The sign hosting the fusion colors everything, since both planets wear it: Venus–Mars in Leo courts an audience; the same pair in Virgo courts by fixing your printer. It also helps to know the conjunction’s opposite number. An opposition takes the same two planets and moves them as far apart as the wheel allows — standoff instead of fusion. Of the two, the conjunction is easier to live with and much harder to see. Most people need someone else to point theirs out.
Asked and answered
What is a conjunction in astrology?
An aspect between two planets standing at or very near the same degree of the zodiac. With no distance between them to negotiate, the planets blend into one compound drive — each acts through the other, permanently. It's also the only major aspect where the pair normally shares a sign.
Is a conjunction good or bad?
Neither, until you name the planets. Venus conjunct Jupiter blends the sky's two friendliest bodies and mostly registers as luck; Mars conjunct Saturn welds drive to restraint and can take a decade to calibrate. The conjunction is the neutral aspect — it amplifies whatever it's made of.
What orb does a conjunction use?
This site counts a conjunction within 8 degrees of exact, widened to 10 when the Sun or Moon is involved — the same orbs the birth-chart calculator applies. Only the opposition is scored as generously; fusion is hard to miss, even at arm's length.
