What is Conjunction in astrology?
A conjunction occurs when two or more planets occupy the same degree or within roughly 8° of each other in the birth chart or by transit. It is the most powerful aspect — planets in conjunction fuse their energies, intensifying and blending their themes in a single point of focus.
- Two planets within ~8° of each other
- Considered the most powerful aspect
- Energy fusion — can be harmonious or tense depending on planets involved
Conjunction Aspect in Astrology
A conjunction occurs when two or more planets occupy the same degree (or within roughly 8° of each other) in the birth chart or by transit. It is the most powerful aspect — planets in conjunction fuse their energies, intensifying and blending their themes in a single point of focus.
The conjunction (☌) is considered the most potent of the five major aspects in astrology. When two planets occupy the same degree, their energies merge — they cannot be easily separated.
Fusion of Energies
Unlike a trine (harmonious flow) or square (creative tension), the conjunction makes two planets function as one. This can be remarkably powerful when the planets are naturally compatible (Venus–Jupiter) or create an internal tension when they are not (Saturn–Uranus).
The Sun-Planet Conjunctions
When a planet is within 17° of the Sun, it is said to be combust — overwhelmed by solar light and potentially weakened in its own expression but also galvanized by the Sun's energy. Exact Sun conjunctions have unique interpretations by planet.
Stelliums
Three or more planets in conjunction form a stellium — a cluster of energy in one sign and house. Stelliums create a dominant life theme but can also indicate imbalance, as so many energies pour into one area.
Transiting Conjunctions
The most powerful transits are conjunctions to natal Angles (Ascendant, MC, IC, Descendant) and personal planets. When outer planets (Saturn, Uranus, Neptune, Pluto) conjunct natal Sun or Moon, major life chapters begin or end.

A conjunction is neither inherently good nor bad — it depends entirely on which planets are conjunct. Sun conjunct Jupiter is expansive and fortunate; Mars conjunct Saturn can feel like energy meeting a wall, building discipline through frustration.
Most astrologers use an orb of 8–10° for major conjunctions, tightening to 1–2° for very specific work. The closer the orb, the stronger the effect.
Moon conjunct Venus in the natal chart blends emotional sensitivity (Moon) with aesthetic appreciation and warmth (Venus) — often indicating someone who is naturally charming, affectionate, and artistically gifted.
When a transiting planet conjuncts a natal planet, it activates that natal planet's themes with heightened intensity for the duration of the transit. A Jupiter transit conjunction to natal Sun brings a period of confidence and expansion.
