Neptune is the eighth furthest planet from the sun in our solar system, the fourth largest in diameter and the third most massive. The planet is named after the Roman God of the Sea.

Neptune was discovered in 1848 and is considered a “new” planet by astrologers as obviously, prior to its discovery it was not used in astrological calculations.

Therefore, opinion on how Neptune affects a chart may vary from one astrologer to the next and some do not take Neptune into account at all.

Neptune rules the imagination, dreams and visions and their expression through art, dance, music, poetry, etc. In a personal chart, Neptune can point to areas where a person may have problems seeing through illusion as well as where someone will find their best creative expression. Those who have a strong Neptune influence may have a spiritual calling or be drawn toward mysticism.

Neptune takes about 14 years to complete its journey through any one sign and is thus considered a “generational planet”, exerting its force on an entire generation.

Since Neptune rules imagination and its expression, the fashionable movies, music, art, etc. of a generation can be influenced by what sign Neptune is in. Neptune also affects a generation’s idealist attitudes and points to areas where a generation will find dissatisfaction with the status quo.


In astrology, Neptune represents the subconscious mind, illusions, and the blurred lines between reality and fantasy.

When working with Neptune’s energy, practitioners often use colors like seafoam green and deep blue, as well as gemstones like aquamarine and amethyst, to enhance their magical endeavors.

This planet’s influence is particularly potent when it comes to divination, psychic abilities, and exploring the mysteries of the deep subconscious.

Neptune’s association with water makes it an ideal ally for rituals involving purification, emotional healing, and connecting with the spiritual depths of the oceanic universe.
