Chart body
Jupiter
Where you expand and what you trust.
In a birth chart, Jupiter describes your growth: where you expand and what you trust.
What it is
More massive than every other planet combined, with the Solar System's most powerful planetary magnetosphere: its magnetic dipole moment is roughly 20,000 times Earth's, while field strength near the planet is tens of times Earth's. Its orbit takes just under twelve years. Its gravity reshapes the orbits of comets and asteroids, ejecting some from the Solar System and redirecting others inward; the popular idea that Jupiter simply shields Earth is too simple.
In a chart: About a year in each sign.
How astrologers have read Jupiter

- Growth, belief, confidence, where you expand and what you trust
AsterNym’s interpretation
At its best
Generosity, perspective and luck that looks suspiciously like optimism repeatedly acted on.
The difficult end
Too much of a good thing. Promising at the size of your enthusiasm rather than your calendar.
What to do with it
Say yes to fewer, larger things. Jupiter makes whatever it touches bigger, including mistakes.
What Jupiter rules
Traditional domicile ruler of Sagittarius and Pisces. If either Sagittarius or Pisces is your rising sign, Jupiter is your chart ruler, the planet a traditional reading treats as standing for you. AsterNym uses the traditional ruler for chart-ruler and dignity calculations and displays any common modern association separately.
| Domicile | Sagittarius · Pisces |
|---|---|
| Exaltation | Cancer |
| Detriment | Gemini · Virgo |
| Fall | Capricorn |
Traditional essential dignity is a symbolic astrological framework, not a measure of astronomical strength or a judgement that a placement is good or bad.
The metal of Jupiter
Tin Sn
Tin became Jupiter's standard alchemical metal. AsterNym uses its role in bronze-making, where a little tin turns copper into a far more useful alloy, as a modern metaphor for Jupiter's traditional themes of increase and expansion.
AsterNym reads it as: Increase: the quality that makes the things around you larger.

Its zodiac position comes from the body's calculated astronomical longitude. Its house is derived from your local birth horizon using AsterNym's declared Whole Sign house system.
