Neptune is associated with realms beyond our everyday reality, an elusive and hard-to-define influence. Neptune is indeed illusive, but the illusion may however lie in our belief that we fully understand its significance, despite having only a brief history of observing it (learn more about it in The origins of astrology).

The deep and the mystical

Neptune moves slowly, taking 165 years to complete a full journey through the zodiac, which means it spends about 14 years in each sign. Named after the Roman sea god Neptune (known in Greek mythology as Poseidon), the planet’s energy is associated with the deep and the mystical.

Neptune and the electromagnetic field

We often hear that our senses are deceptive, that what we perceive as reality is, in truth, an illusion. Our sight and touch tell us that we are in an “empty space” with just some air around us, yet we are actually immersed in a vast ocean of electromagnetic frequencies.

This ocean of electromagnetism is primarily created by earth’s magnetic field, along with radiation from the sun and moon. The planets, and perhaps many other factors, also contribute subtle layers to this field.

Conventional astrology often places great emphasis on the planets, but when we view astrology as a way of analyzing the electromagnetic field that surrounds us, it gives us a more nuanced view. Rather than the nearly fated role often attributed to the planets, also in modern astrology, their influence on individuals is far subtler (see more on this topic in How electromagnetic astrology affects us humans).

More simply, Neptune represents inspiration and dreams. Through them, we bridge the gap between our conscious self and our subconscious, or perhaps our higher self. Because of this, Neptune is often associated with artistic inspiration and creativity.

Ego dissolution and altruism

When we move beyond our usual reality, concepts and structures, as well as our sense of self, begin to dissolve. Neptune, therefore, is linked with ego dissolution, merging with the greater whole, idealism, impersonal love and altruism.

For most people, however, Neptune’s energy can bring confusion, anxiety and a sense of losing touch with reality. Consequently, Neptune is also associated with escapism, including substance use and reckless behavior.

Neptune’s rulership

Inspiration, dreams, fantasies, artistry and the dissolution of ego are all qualities shared with the sign of Pisces. Modern astrologers generally consider Neptune to be the ruling planet of Pisces.

Interpreting Neptune in astrology

Since Neptune moves so slowly through the zodiac, people born around the same time will share the same Neptune placement in their birth charts, making it what is known as a generational planet.

In an individual birth chart, Neptune’s placement indicates where we have creative ability and where we might feel inspired or compassionate, as well as where we might have psychic sensitivity. However, this type of energy can be challenging for many people. Humans are, after all, social beings, and many struggle with prolonged solitude and introspection.

It is helpful to remember that Neptune, like the other planets, only adds a subtle influence to the energy field around us, and may not have a major impact on an individual level.

When viewed at a societal level, however, Neptune’s slow journey through the zodiac can subtly influence enough people to bring about shifts within society. Neptune’s gradual journey through the zodiac can inspire shifts that influence entire generations and even shape society’s cultural currents.

What zodiac signs does Neptune rule?

Neptune rules Pisces, emphasizing spirituality, creativity and emotional depth. Its influence is often subtle but profound, encouraging individuals to transcend the material world and seek universal truths. In other words, Neptune rules spirituality.

What does Neptune’s position in a natal chart show?

Conventional astrologers think that Neptune’s position reveals where individuals are most likely to experience dreams, illusions or spiritual growth.

In astrology, the planet Saturn marks the end of the material world and known universe, with Uranus, Neptune and Pluto ruling energies that lie beyond our normal senses. These are also called the outer planets in the solar system.

Like the other outer planets, Neptune moves slowly through the zodiac, influencing generations of people rather than individuals, urging humanity to evolve on a spiritual level. It is therefore seen as one of the transpersonal planets.

How does Neptune’s influence compare to other outer planets like Uranus or Pluto?

Neptune, as an outer planet, works on a collective level. Unlike Uranus, which triggers sudden changes, or Pluto, which represents transformation and rebirth, Neptune’s role is subtler, dissolving boundaries to inspire unity and universal compassion.

What are Neptune’s more negative manifestations?

On the downside, Neptune can lead to confusion, deception or escapism. These negative manifestations may show up as addiction, avoidance of responsibility or unrealistic expectations, especially when one struggles to balance the material world with spiritual aspirations.

Why is Neptune considered a higher octave of Venus?

Venus governs love, beauty and relationships on a personal level, while Neptune elevates these themes to a universal scale, emphasizing selfless love, divine inspiration and connection with the divine. This link highlights Neptune’s role in encouraging artistic expression and compassion.

How does Neptune interact with planets like Saturn or Mercury?

Neptune contrasts with Saturn, which represents the existing order and material limitations. Where Saturn focuses on structure, Neptune dissolves it to encourage dreaming and imagination.

With Mercury, Neptune can enhance creativity and intuition but might also cloud rational thinking or communication.

What lessons does Neptune offer on a personal and collective level?

Neptune invites individuals to transcend the mundane and embrace the interconnectedness of life. On a personal level, this involves exploring spirituality, intuition and empathy. On a collective level, Neptune inspires movements rooted in peace, unity and a shared vision of a better world.

What are the houses in astrology and how are they related to Neptune?

In conventional astrology, the astrological houses are thought to explain different aspects of our lives and how they are influenced by the planets. There are many house systems and they all place the planets differently, making houses an unreliable part of astrology (read more about it here).

There is a general association of Neptune with the twelfth house, which is related to the subconscious – secrets, spirituality, solitude and the unconscious mind.
