Since the invention of the telescope, Western astrology has incorporated Uranus, Neptune, Ceres, Pluto, and other bodies into its methodology. The outer modern planets Uranus, Neptune and Pluto are often called the collective or transcendental planets.

Neptune is another of the outer planets. It takes Neptune about 165 years to complete its rotation around the zodiac.  Neptune stays in the same sign about 10 to 15 years. It shows how serreal and mysterious our life will be. A person with a strong Neptune influence will have an active imagination and many times inconsistent perceptions of reality. Neptune rules the ocean and all it's mysteries in Greek mythology. Neptune is thought to be the planet of deception, illusion, and imagination.  Dreams, abstract thought, illusion and the secretive are all goverened by Neptune.  Sometimes we do need to take a chance and explore fantasies or get in touch with our sensitivity, so the impact is not entirely negative. However, the presence of Neptune can be associated with substance abuse as an escape from reality. Neptune rules the Zodiac Sign of Pisces.

Neptune governs hospitals, prisons, mental institutions, and any other place, such as a monastery, that involves a retreat from society. Its appearance coincided with the discovery of anesthetics and hypnotism. In political terms, Neptune was linked to the rise of nationalist movements throughout Europe in countries like Germany, Italy, Hungary, Ireland, and Serbia, seeking independence for their nations inspired by an idealized past of legend. It was also linked to the rise of socialism and the beginnings of the welfare state. Neptune coincided with the utopian ideals of Communism, when Marx and Engels first published 'The Communist Manifesto' in 1848. Neptune also represents the day of Friday, alongside Venus.
