Neptune (♆) is the ruling planet of Pisces for most Western astrologers. Prior to the discovery of Neptune, Jupiter was considered the ruler of Pisces. Some modern astrologers consider Jupiter a co-ruler of Pisces. Some astrologers do not believe that Neptune rules any particular sign, even though they may use the planet in chart interpretation.
Neptune is associated with illusion, deception, religions, spirituality, mass media, music, drugs, extreme sensitivity, psychic phenomena, and altered states of consciousness. The discovery of Neptune in 1846 coincided with the discovery of anesthetics and hypnotism.
