Core function
In astrological interpretation, Neptune is associated with imagination, ideals, dissolution and sensitivity. This is a symbolic function, not a scientifically demonstrated influence.
How to read it in a chart
Start with Neptune 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
Neptune is the modern ruler of Pisces; Jupiter is its traditional ruler. Rulership creates a network between signs, planets and houses that astrologers use to connect different parts of a chart.
Astronomical classification
Neptune orbits the Sun in about 165 Earth years (60,190 Earth days), so it stays in each zodiac sign for well over a decade. (Source: NASA — Neptune facts.)
