Core function
In astrological interpretation, Jupiter is associated with growth, meaning, opportunity and belief. This is a symbolic function, not a scientifically demonstrated influence.
How to read it in a chart
Start with Jupiter as the function. Add the sign for style, the house for life area and aspects for modification. Avoid treating the sign alone as the complete meaning.
Sign rulership
Jupiter rules Sagittarius and is the traditional ruler of Pisces (Neptune is Pisces’ modern ruler). Rulership creates a network between signs, planets and houses that astrologers use to connect different parts of a chart.
Astronomical classification
Jupiter is the largest planet in the solar system. It orbits the Sun in about 12 Earth years (4,333 Earth days), which is roughly why it spends about a year in each zodiac sign. (Source: NASA — Jupiter facts.)
