8th house synastry overlay
8th house synastry puts their planet in your 8th house: they get access to the material you do not hand over casually — money, fear, sex.

How an 8th house overlay feels
The eighth house covers intimacy, shared resources and transformation, so overlays here tend to be intense. The planet person often reaches the house person's private emotional life, sexuality and fears, and money or property may become entangled. These overlays are associated with deep bonds that change both people — and with jealousy and control when trust is missing. They are rarely neutral: people either feel profoundly connected or uncomfortably exposed.

Their Jupiter in your 8th house
Their Jupiter may bring financial benefit through the relationship and a trusting, generous intimacy.
Their Saturn in your 8th house
Their Saturn makes intimacy cautious and serious. Shared debts or responsibilities need clear agreements.
Their Uranus in your 8th house

Their Neptune in your 8th house
Their Neptune creates a mystical, boundary-less intimacy. Clarity about money and trust is essential.
Their Pluto in your 8th house
Their Pluto is one of the most intense overlays in synastry: obsession, transformation and power over each other.
Overlays run both ways: check where your planets fall in their chart too. Houses show where the other person’s influence is felt; aspects between the charts show how well the two of you actually get along.
House person and planet person
Who feels an 8th house synastry overlay more?
Most synastry writing says the house person feels an 8th house overlay more intensely: the planet person reaches what they keep guarded — sex, money, fear, the things not said aloud — and they feel exposed by it. The planet person tends to feel fascination and a pull toward depth, sometimes a wish to control; the imbalance is the reason the overlay gets called obsessive.
By rising sign
Whose Sun lands in your 8th house
With whole-sign houses your 8th house is the sign 7 steps on from your rising sign. A partner born while the Sun was in that sign has their Sun in your 8th house; their other planets need their own chart.
| Your rising sign | Your 8th house | Partner’s Sun there if born |
|---|---|---|
| Aries rising | Scorpio | October 23 – November 21 |
| Taurus rising | Sagittarius | November 22 – December 21 |
| Gemini rising | Capricorn | December 22 – January 19 |
| Cancer rising | Aquarius | January 20 – February 18 |
| Leo rising | Pisces | February 19 – March 20 |
| Virgo rising | Aries | March 21 – April 19 |
| Libra rising | Taurus | April 20 – May 20 |
| Scorpio rising | Gemini | May 21 – June 20 |
| Sagittarius rising | Cancer | June 21 – July 22 |
| Capricorn rising | Leo | July 23 – August 22 |
| Aquarius rising | Virgo | August 23 – September 22 |
| Pisces rising | Libra | September 23 – October 22 |
Sun-sign dates shift by a day in some years. Equal and Placidus houses can give a different answer near a cusp; the synastry calculator places every planet of both charts.

money, possessions and self-worth
House type
succedent
This house pairs with the 2nd across the chart — money, possessions and self-worth — and the two work as one axis. A planet landing here looks straight across at that house, so the two readings belong together rather than separately.
It is a succedent house, which follows an angle and describes what accumulates there rather than what initiates. Its natural ruler is Pluto, so a partner's Pluto arriving here doubles the theme rather than adding a new one.
The 8–2 axis
Shared resources, exposure and what is not said aloud sits opposite money, possessions and self-worth. A planet in one faces the other across the chart, so an overlay here is always a statement about both — they get access to the material you do not hand over casually — money, fear, sex; at the 2nd-house end, they affect what you consider yourself worth, and often what you spend.
