Quick answer
A conjunction in astrology is two planets sitting within a few degrees of each other, at about the same point in the zodiac. Their meanings blend into one combined drive, which is why it is usually called the strongest aspect. Whether it feels easy or difficult depends entirely on which two planets are joined. Venus conjunct Mars and Saturn conjunct the Moon are both conjunctions and feel very different.
Key takeaways
- A conjunction is two planets at nearly the same degree, and their meanings fuse rather than negotiate.
- It is neither soft nor hard on its own; the planets involved decide the tone.
- Venara counts a conjunction within 7 degrees, or 8 when the Sun or Moon is involved, and closer is stronger.
- The pattern to watch is the blind spot: when two drives are fused, it is hard to see either one on its own.
A conjunction is two planets sitting at nearly the same spot in the zodiac, usually within a few degrees. Instead of two separate drives talking to each other, you get one combined drive, and it is almost always felt strongly.
Every other aspect describes a relationship between two planets: cooperation, friction, a tug of war. The conjunction describes a merger. That makes it the simplest aspect to define and, in some ways, the hardest to see in yourself, because when two things are fused you stop noticing that there were ever two. This guide covers how close planets need to be, why the conjunction has no fixed tone, what the common love conjunctions tend to feel like, and the blind spot to watch.
What is a conjunction in astrology?
A conjunction is an aspect of 0 degrees: two planets at about the same degree of the zodiac. In practice, planets are rarely at the identical degree, so astrologers allow a range, called the orb.
A few plain definitions. A planet here includes the Sun and Moon, as astrologers traditionally count them. An aspect is a meaningful angle between two planets, and it describes how those two parts of you interact. The five major aspects are the conjunction (0 degrees), sextile (60), square (90), trine (120) and opposition (180). If the others are new to you, astrology aspects explained covers them all.
Think of the conjunction as two people sharing one seat. They cannot avoid each other, they move together, and from the outside it can be hard to tell where one ends and the other begins.
How close do planets need to be for a conjunction?
Close enough to fall within the orb, and there is no universal orb. Most astrologers count a conjunction somewhere between 6 and 10 degrees, and many allow a wider range when the Sun or Moon is involved.
For a concrete example, here are the limits Venara uses:
- Conjunction between two planets: within 7 degrees.
- Conjunction involving the Sun or Moon: within 8 degrees.
- Closer is stronger. A 1 degree conjunction is felt far more than a 7 degree one, and many astrologers treat anything under about 3 degrees as especially strong.
Two details worth knowing. First, aspects are measured in degrees, not signs, so an out-of-sign conjunction is possible: Venus at 28 degrees Cancer and Mars at 3 degrees Leo are 5 degrees apart and conjunct, even though the signs differ. The fusion still happens, but each planet keeps a little of its own sign's manner. Second, three or more planets conjunct in a chain form a cluster, and if they share a sign or house astrologers call it a stellium.
Is a conjunction good or bad?
Neither. The conjunction is the one major aspect with no built-in tone. Sextiles and trines are soft, squares and oppositions are hard, and the conjunction simply amplifies whatever the two planets bring.
Sue Tompkins puts it in terms of the planets themselves: a conjunction between two planets that get along in nature will feel easy, and one between planets with opposing natures will feel tense. Venus and Jupiter together tend to feel generous. Mars and Saturn together tend to feel like acceleration with the brake half on. Both are conjunctions.
Here is a comparison of common conjunctions that touch love, so you can see the range.
| Conjunction | What fuses | Often feels like | Pattern to watch |
|---|---|---|---|
| Sun conjunct Moon | Identity and emotional need | Consistent, knows what it wants | Little inner debate, so blind spots go unchecked |
| Sun conjunct Venus | Identity and love | Charming, values being valued | Self-worth tied to being liked |
| Moon conjunct Venus | Need and affection | Warm, easy to be close to | Needing to be needed |
| Venus conjunct Mars | Affection and desire | Magnetic, direct in pursuit | Confusing chemistry with fit |
| Venus conjunct Saturn | Affection and caution | Loyal, slow to open | Withholding until it feels safe, which may be never |
| Venus conjunct Pluto | Affection and intensity | All in, deep bonds | Control dressed as devotion |
| Moon conjunct Mars | Feeling and action | Quick, protective, passionate | Anger arriving before the hurt is named |
None of these is a verdict. Each describes a style with a strength and a watch point, and the house and sign shift the details further.
What does a conjunction feel like from the inside?
From the inside, a conjunction usually does not feel like anything, and that is the point. When two drives have always operated as one, it seems normal. You only notice it when someone else describes the same two things as separate.
Take Sun conjunct Mercury, one of the most common conjunctions because Mercury never travels more than about 28 degrees from the Sun. People with it often experience their thoughts as simply who they are. Disagreeing with their idea feels like disagreeing with them. They rarely notice this until a partner points out that "I think you are wrong" and "I think less of you" are different sentences.
That is the general pattern to watch with any conjunction: the blind spot. Fused planets are hard to see individually. Venus conjunct Mars can struggle to tell love from desire. Moon conjunct Saturn can struggle to tell caution from sadness. The strength of the conjunction is focus and intensity. The cost is that the two things it fuses stop being available separately unless you learn to pull them apart on purpose.
What does a conjunction mean in love?
In love, a conjunction between two of the relationship planets (Sun, Moon, Venus, Mars) tends to make that part of your love style strong, obvious and hard to fake. Partners usually see it quickly.
Liz Greene wrote about how the planets in a chart describe inner figures that people often meet through their partners. With a conjunction, two of those figures have merged, so what you look for in a partner tends to be more single-minded. Venus conjunct Mars wants a partner who is both lovable and exciting, and finds it hard to accept one without the other. Moon conjunct Venus wants comfort and romance from the same person and may not realize those can come from different places.
In synastry, the comparison of two people's charts, conjunctions between one person's planet and the other's are among the strongest links astrologers look at. Your Venus on their Mars, your Moon on their Sun: these tend to feel like instant recognition. They do not by themselves make a relationship work, but they usually explain why it started fast.
What does a conjunction mean at work?
At work, a conjunction is often the trait colleagues would name first about you, because it is concentrated and consistent. A few examples:
- Mercury conjunct Mars: quick, decisive thinking, sharp in a debate. Watch point: words that cut before you meant them to.
- Sun conjunct Saturn: serious, responsible, built for the long haul. Watch point: treating rest as failure.
- Mercury conjunct Jupiter: big-picture thinking, natural teacher. Watch point: skipping details on the way to the vision.
- Mars conjunct Jupiter: energy and appetite for large projects. Watch point: overcommitting.
- Moon conjunct Mercury: thinks by talking, communicates feeling clearly. Watch point: needing to process out loud when a decision is needed quickly.
The house tells you where the fused drive shows up most. Sun conjunct Saturn in the 10th house puts the seriousness squarely into career. The same pair in the 4th puts it into home and family responsibility.
What happens when a planet is conjunct the Sun?
A planet conjunct the Sun gets a special set of names. A planet within about 8 degrees of the Sun is traditionally called combust, and the older idea is that it is overwhelmed by the Sun's light, so its own expression is harder to see. A planet within about 17 arcminutes of the Sun's center is called cazimi, "in the heart of the Sun", and is traditionally seen as strengthened.
Mercury and Venus are the planets most often combust, because they orbit inside Earth's orbit and never stray far from the Sun as seen from here. Our guide to combust and cazimi planets goes through the traditional readings and how much weight modern astrologers give them. For most readers, the useful takeaway is simply that a Sun conjunction folds that planet into your sense of identity.
Is the conjunction really the strongest aspect?
Most astrologers say yes, because the two planets are at the same point and there is no distance to soften the effect. In practice, the strongest aspect in your chart is usually the tightest one, whichever type it is. A 1 degree square can be felt more than a 6 degree conjunction.
It is worth being plain about what all this is. The positions of the planets are real astronomy, and whether two planets were within a few degrees at your birth is a fact anyone can check against an ephemeris. The meaning of that closeness is a symbolic tradition, refined over centuries, and not a measured property of your personality. Many people find the description of a fused drive very recognizable, and that is the useful test: does it describe something you can see in your own week?
What should you do with your conjunctions?
Learn to see the two planets separately. Three steps:
- List every conjunction under 3 degrees. Those are the ones worth your attention first. Write the two planets and one sentence about what each one stands for on its own.
- Catch the fusion in the wild. For a week, notice moments when the two drives fire together. Sun conjunct Mercury: when did a disagreement feel like an insult? Venus conjunct Mars: when did attraction and affection arrive at the same instant?
- Practice pulling them apart once. Pick one situation and consciously act from only one of the two planets. That is how a blind spot becomes a choice.

Frequently asked questions
What does conjunction mean in astrology?
A conjunction means two planets are at about the same degree of the zodiac, within a few degrees of each other. Their meanings combine into one. Sun conjunct Mercury, for example, blends identity with thinking, so the person tends to be identified with their ideas. The conjunction is generally treated as the strongest aspect because there is no distance between the two drives.
Is a conjunction a good or bad aspect?
Neither by itself. A conjunction fuses two planets, and the result depends on which two. Venus conjunct Jupiter tends to feel generous and warm. Mars conjunct Saturn tends to feel like driving with the brake on. Astrologers call the conjunction neutral for this reason: it intensifies whatever the two planets bring, pleasant or difficult.
How many degrees is a conjunction?
There is no single agreed number. Most astrologers count a conjunction within about 6 to 10 degrees, and allow a little more when the Sun or Moon is involved. Venara uses 7 degrees, or 8 with the Sun or Moon. Within any limit, a 1 degree conjunction reads as much stronger than a 7 degree one.
What does Venus conjunct Mars mean?
Venus conjunct Mars blends affection with desire, so attraction and love tend to arrive as one package. People with this aspect are often described as magnetic, direct about what they want and quick to pursue it. The strength is obvious warmth and chemistry. The pattern to watch is mistaking a strong physical pull for a good long-term fit.
Can planets be conjunct in different signs?
Yes. Aspects are measured in degrees, not signs. Venus at 29 degrees Aries and Mars at 2 degrees Taurus are 3 degrees apart, which is a close conjunction even though the signs differ. Astrologers call this an out-of-sign conjunction. It still fuses the two planets, but each keeps a little of its own sign's style, so the blend is less seamless.
