Conjunction
Two planets merging energy - intensified and unified.
A conjunction occurs when two planets occupy the same degree (within ~8°). Their energies fuse, amplifying each other. This can be harmonious or challenging depending on the planets involved. It's the most powerful aspect.
Example
Sun conjunct Moon at birth = New Moon baby, blending identity with emotions.
Cultural Context
Ancient astrologers called conjunctions 'corporal' aspects because the planets were in the same 'body' of the zodiac. Great Conjunctions of Jupiter and Saturn (every 20 years) were used to predict the rise and fall of kingdoms.
Famous Example
The 2020 Jupiter-Saturn Great Conjunction at 0° Aquarius was the closest since 1623 and marked the shift from earth to air sign conjunctions for the next 200 years — astrologers predicted major societal changes around technology and social structures.
Did You Know?
When three or more planets conjunct in a tight cluster, it's called a 'stellium.' Having a stellium concentrates enormous energy in one area of life — some of history's most impactful people have stelliums in their charts.
