What a conjunction means
A conjunction is the 0° aspect: seen from Earth, two planets line up side by side in the sky. Most conjunctions fall within one sign, so both planets share the same element and style. Instead of two parts of you holding a conversation, you get two parts that have merged, the way two colors mixed together make a new shade rather than a pattern.
In life, a conjunction tends to show up as intensity. The house it occupies gets extra weight, and the themes of both planets are hard to pull apart. Many people find their conjunctions are so woven into who they are that they barely notice them until someone else points them out.
How a conjunction feels, with examples
Sun conjunct Mercury links identity with thinking: you may speak in a way that sounds unmistakably like you, and criticism of your ideas can feel personal. Venus conjunct Mars blends affection with desire, so attraction tends to be quick, warm and physical. Moon conjunct Saturn ties feelings to responsibility; you may have learned early to handle emotions carefully and privately, and you often become the steady one others lean on.
Some pairings are more charged. Mars conjunct Pluto puts a lot of force behind wanting something, which can read as determination or as all-or-nothing pressure. Jupiter conjunct Neptune enlarges imagination and idealism—inspiring, though sometimes vague about limits.
Working with a conjunction
Start by naming what each planet wants on its own. With Moon conjunct Saturn, the Moon wants comfort and Saturn wants structure; once you see both needs, you can stop treating rest as something you have to earn. Notice when one planet drowns out the other, and give the quieter one a deliberate outlet. A conjunction is concentrated energy, and it works best when you direct it rather than letting it run on autopilot.
It also helps to look at the sign and house the pair shares. Venus conjunct Mars in the 10th house might pour that warmth and drive into visible work, while the same pair in the 4th might pour it into home life. The sign describes the style, the house describes the setting, and together they show where your merged planets most want to be expressed.
Orb, planets and strength
Orb is the distance from an exact 0°. CAZIMI counts a conjunction up to 6° apart, the widest orb of the five major aspects, because blending planets are felt even at some distance. Within a degree or two, the pair acts almost as one; near the 6° edge, the link is softer and easier to separate.
The planets involved matter too. Conjunctions among the Sun, Moon, Mercury, Venus and Mars feel personal and immediate. When Uranus, Neptune or Pluto joins a personal planet, a generational theme becomes part of your character. When two outer planets meet, the conjunction is shared by everyone born over a span of months or years. Traditional astrology even has a name for a planet sitting almost exactly at the Sun’s center: cazimi, “in the heart of the Sun.”
Questions people ask
Is a conjunction a good or bad aspect?
Neither by default. A conjunction is a merger, so its tone depends on which planets meet. Venus with Jupiter tends to feel generous and easy; Mars with Saturn can feel like pressing the gas and the brake at once. Most people experience their conjunctions as a mix of strength and challenge in the same area of life.
What is the strongest aspect in astrology?
The conjunction is often considered the most intense aspect, because the planets act as one rather than interacting from a distance. Strength also depends on orb, though: an exact square can be felt more than a wide conjunction. Look at how tight each aspect is and whether personal planets like the Sun or Moon are involved.
What does it mean when a planet is conjunct the Sun?
A planet close to the Sun blends its themes into your core identity. Mercury near the Sun, for example, makes your thinking a central part of who you are. Traditional astrology calls a planet very near the Sun “combust,” hidden in its glare, and one almost exactly at its center “cazimi,” a placement long seen as especially favored.
