Neptune
Blurred boundary: where a person is inspired and where they are deceived
What it means
Neptune – a blurred boundary: where a person is inspired and where they are deceived, where compassion turns into an inability to say no. It governs imagination and the ability to let go, and when imbalanced – it produces illusions instead of plans.
In balance
Imagination, compassion, ability to let go
Out of balance
Illusions instead of plans, avoidance of the unpleasant, blurred responsibility
What this object is
one hundred and sixty‑five years per cycle, about fourteen years in a sign
Neptune was discovered in 1846 by calculation rather than observation: its position was derived from the deviations in Uranus’s orbit and then found almost exactly where predicted. Its orbital period is about 165 years, spending roughly fourteen years in each sign.

How to read in your chart
Like Uranus, Neptune's sign is generational; the house and aspects give personal detail. Neptune aspects to the Moon or Venus often indicate idealisation, to Mercury suggest difficulty phrasing precisely and a tendency toward beautiful but vague language.
