What is Eros in astrology?
Eros (asteroid 433) was discovered in 1898 and was the first near-Earth asteroid to be identified. He is named for the Greek god of erotic love, who in myth is sometimes the primal force of creation and sometimes the mischievous archer who shoots gods and mortals into the pain and pleasure of desire.
In a natal chart, Eros shows the signature of what activates your passion. This is different from Venus, which describes your general aesthetic and your style of pleasure, and different from Mars, which describes your drive. Eros is specifically erotic: the specific thing that makes someone feel alive in the body and pulled toward another person or creative project.
How to read your Eros placement
Start with the sign. Fire-sign Eros wants heat, pursuit, and the first charged moment. Earth-sign Eros wants sensual, patient, embodied desire that takes its time. Air-sign Eros wires erotic charge to language, curiosity, and the right conversation. Water-sign Eros needs emotional safety and depth for desire to fully arrive.
With an exact birth time, the house placement locates the domain where your erotic life is most active: the 5th house as creative-romantic expression, the 8th as transformative intimacy, the 11th as the unconventional erotic community, the 12th as private, often hidden erotic life.
Eros in synastry
Eros is one of the most useful asteroids for synastry, the comparison of two people's charts. When one person's planets fall on another person's Eros, an erotic charge is likely. Eros to Eros contacts, Eros to Venus, and Eros to Mars are the classical combinations that show whether the chemistry between two people has a specifically erotic signature rather than a purely platonic or aesthetic one.

Frequently Asked Questions
What is Eros in astrology?
Eros (asteroid 433) is named for the Greek god of erotic love. In a natal chart, Eros shows the specific signature of what activates your desire. Where Venus describes your general style of attraction and pleasure, Eros describes the erotic charge, the thing that wakes up your passion rather than your taste.
How do I find my Eros sign?
Enter your birth date, time, and place above. The calculator uses NASA JPL small-body orbital elements to compute asteroid 433 Eros at your birth moment and returns the sign, degree, and house (when birth time is known).
Do I need an exact birth time for Eros?
No. Eros moves relatively quickly but not fast enough to cross a sign in a single day, so an approximate birth date places him reliably. An exact birth time adds the house placement, which describes the life area where your erotic energy most naturally activates.
What does my Eros sign mean?
Eros's sign describes your erotic signature. Eros in Scorpio wants transformative depth; Eros in Aquarius wants the unusual and the free; Eros in Cancer wants tenderness before heat. The interpretation returned walks through the specific turn-on pattern of the placement and the shadow pattern when the erotic life is denied or misunderstood.
