The quincunx, astrology’s 150° aspect: two planets learning to adjust
The quincunx, also known as the inconjunct, is the 150° aspect: two planets five signs apart, nearly opposite but not quite. Their signs share no element, no modality and no polarity, so nothing tunes them to each other in advance. What it asks for is neither a fight nor a surrender but an adjustment: small, repeated corrections that slowly turn into a real skill.
Why 150° behaves like no other aspect
The word is Latin: quincunx means “five twelfths”, and 150° is exactly five twelfths of a circle. Gardeners use it for trees planted like the five on a die, one at each corner and one in the middle. In astrology, it names a gap of five signs between two planets.
Set it beside the major aspects in the aspects encyclopedia. A trine joins two signs of the same element; a square, two of the same modality; an opposition, two that share both modality and polarity; a sextile, two of the same polarity. The quincunx keeps none of those threads: Virgo, mutable feminine earth, looks sideways at Aries, cardinal masculine fire.
Hence its peculiar flavour: the two planets don’t understand each other by instinct, yet they never collide head-on either. Building the bridge is up to you.
Which signs are quincunx each other?
Every sign has two quincunx partners, which makes twelve pairs in all. Two of them hide a family tie: Taurus and Libra are both ruled by Venus, while Aries and Scorpio share Mars as their traditional ruler. In those pairs, the quincunx links two faces of a single planet. Here is the full list, sign by sign:
- Aries: Virgo, Scorpio
- Taurus: Libra, Sagittarius
- Gemini: Scorpio, Capricorn
- Cancer: Sagittarius, Aquarius
- Leo: Capricorn, Pisces
- Virgo: Aquarius, Aries
- Libra: Pisces, Taurus
- Scorpio: Aries, Gemini
- Sagittarius: Taurus, Cancer
- Capricorn: Gemini, Leo
- Aquarius: Cancer, Virgo
- Pisces: Leo, Libra
To find these pairs without looking anything up, start from the opposite sign and take one step sideways. Capricorn faces Cancer; its two neighbours, Sagittarius and Aquarius, are Cancer’s quincunxes.
What orb should you use for a quincunx?
The quincunx is a minor aspect, and it is read tight. On My Birth Chart, its reference orb is 2.5°: any wider and the conversation between the two planets gets too blurry. Orb has its own entry.
Work it out in degrees, around the full 360° of the zodiac: a Moon at 9° Gemini sits at 69°, Saturn at 10° Capricorn at 280°. The gap is 211° one way and 149° the other; you always keep the shorter one. At 149°, that is a quincunx with a 1° orb, crisp and clear.
A quincunx can also straddle a sign boundary. A planet at 29° Aries and another at 1° Libra are 152° apart: the aspect is there, with a 2° orb, even though the two signs face each other. Astrologers call this an out-of-sign, or dissociate, aspect, and it keeps a trace of the opposition’s face-off.
What does a quincunx mean in a natal chart?
Its keyword is adjustment. Two genuine needs that never openly clash still get in each other’s way the moment you try to serve both at once. It feels like a slight misalignment, a sense of constantly having to correct course.
Picture a Moon at 18° Cancer and Jupiter at 17° Sagittarius, 149° apart. The Moon wants a nest, landmarks, familiar faces; Jupiter wants horizon, fresh ideas, the open road. Chasing all of it at the same time wears you out. Taking turns, travelling far while keeping an evening ritual, bringing the wider world home: that is how the friction becomes a way of living.
Next, look at the two houses involved: they show which areas of your life have to calibrate to each other. Tradition also links the quincunx with the 6th and 8th houses, the two that sit five signs from the 1st: daily habits, and what you share.
The lever: stop trying to merge the two planets into one, and arrange how they live side by side. Once worked on, a quincunx brings unusual flexibility, the knack of switching registers without losing the thread.
Two quincunxes leaving from the same planet, with a sextile at their base, draw a yod: all the tension points toward the planet at the tip.
Spotting a quincunx on your chart wheel, in four steps
The My Birth Chart wheel only draws the major aspects, so a quincunx gets no line of its own: you find it by eye. Calculate your chart with your birth time, open its wheel (how the wheel works), then:
- Write down each planet’s sign and degree; the degree is printed inside its chip.
- For each planet, locate its two quincunx signs.
- Look there for a planet at a similar degree, no more than 2.5° off.
- Near the very start or end of a sign, redo the count in degrees: an out-of-sign quincunx may be hiding in the neighbouring sign.
Still unsure? Ask Vega “Where is my Moon relative to my Jupiter?”: a curved arrow links the two planets on the wheel, with their distance in degrees. Anything from 148° to 152° is a quincunx. She reads your calculated chart, so you can also just ask her.
Calculate your chart, note each planet’s degree and look for 150° gaps: your quincunxes show where you already know how to adjust.
