Major Aspects
Conjunction
Astrology meaning, traditional reading, and frequently asked questions.
Quick Definition
Two planets within a few degrees of each other — they blend their energies and act as one combined force.
What Conjunction Means
A conjunction is formed when two planets sit within a few degrees of each other in the same zodiac sign — traditionally within an orb of 8°–10° for the luminaries and somewhat tighter for other planets. The planets merge, blending their meanings into a single combined expression. Conjunctions are neither inherently easy nor difficult; their tone depends on the planets involved. Mars conjunct Venus blends passion with affection; Saturn conjunct Sun blends discipline with identity. They are the strongest of the major aspects.
How to Spot Conjunction in Your Chart
To find a Conjunction in your chart, compare the zodiac degrees of two planets. A Conjunction forms when the two planets sit a specific number of degrees apart — most astrology software draws the aspect automatically with a coloured line between the two planets on the chart wheel.
The tightness of the aspect matters: the closer the two planets are to the exact degree separation, the stronger the Conjunction is read. Astrologers usually allow an orb of a few degrees on either side, with tighter aspects (within 1°–3°) producing the strongest readings.
Concrete Example
A natal Mercury conjunct Sun within 1° is called “cazimi” in traditional astrology — Mercury is said to be sitting in the heart of the Sun, which is read as a uniquely dignified placement.
What Conjunction Traditionally Indicates
Traditional astrology, going back to Ptolemy’s Tetrabiblos, divided aspects into “easy” and “hard” categories. Conjunctions, sextiles, and trines were considered cooperative or beneficial; squares and oppositions were considered tense or challenging. The Conjunction fits this classical typology and carries its traditional reading.
Modern astrology has largely retained the classical aspect meanings but has softened the moral framing — “hard” aspects are now widely read as growth-producing rather than as bad luck, and “easy” aspects are recognised as gifts that can be wasted if not consciously worked. The geometry is the same; the interpretation is more dimensional.
Frequently Asked Questions
How tight does a conjunction need to be?
Traditional astrology uses generous orbs — 8°–10° for the Sun and Moon, 6°–8° for other planets. Modern astrology has tightened these somewhat, with some astrologers using as little as 3°–5°. Tighter conjunctions are read as stronger and more inescapable.
Is a conjunction a good aspect?
It depends on the planets. A Jupiter–Venus conjunction is traditionally called fortunate; a Mars–Saturn conjunction is traditionally called difficult. The conjunction itself is neutral — it amplifies whatever the two planets are doing.
What is the difference between a conjunction and a stellium?
A conjunction is between two planets. A stellium is a cluster of three or more planets, usually all in the same sign or house, often within conjunction-level orbs of one another. A stellium is essentially several conjunctions stacked.
Can conjunctions happen across sign boundaries?
Yes — a planet at 29° of one sign and a planet at 1° of the next are technically only a couple of degrees apart, but they sit in different signs. Some astrologers count this as a conjunction; others, especially in traditional astrology, do not because the sign change breaks the unity.

Square
Two planets 90° apart — a tense, friction-creating aspect that pushes for action and growth.
Trine
Two planets 120° apart — a flowing, harmonious aspect; the energies cooperate without resistance.
Sextile
