What is my Chiron sign?
Your Chiron sign is the zodiac sign the small body Chiron was in when you were born. Chiron orbits between Saturn and Uranus on a stretched orbit, so it spends from about 2 years (Virgo, Libra, Scorpio) to 8 or 9 years (Pisces, Aries) in a sign, counting its retrograde back-and-forth, and everyone born in the same stretch shares it. Astrologers read its sign and house as an area of old hurt that can turn into a skill for helping others. The sign needs only your birth date; the house needs your time.
Chiron's sign and degree on your birth date, its house if you know your time, and the planets it touches in your chart.
How it is calculated
Chiron's position comes from the Shymea engine. Chiron is not in the planetary ephemeris itself, so the engine builds its orbit from JPL Horizons orbital elements and observes it from Earth with Skyfield on the DE442 ephemeris, the same reduction the planets get. The engine's tests put the error under about 0.1° for births between 1950 and 2075, well inside a sign or house boundary.
The house is the Placidus house from your birth time and place. The aspects listed are measured from the engine's longitudes: conjunction, opposition, square and trine within 6°, sextile within 4°, to the Sun through Saturn. Without a birth time the Moon is left out, because it moves about 13° a day.
Common questions
- How long does Chiron stay in a sign?
- From about 2 years to 8 or 9 years, counting the retrograde back-and-forth over a sign line. Chiron moves fastest when it is nearest the Sun, through Virgo, Libra and Scorpio, and slowest when it is farthest, through Pisces and Aries. That is why some Chiron signs are shared by much larger age groups than others.
- Do I need my birth time for Chiron?
- Not for the sign. Chiron moves no more than about 0.13° a day, so the date alone almost always fixes it. You need the time for the house, and for any aspect to the Moon.
- What is the difference between my Chiron sign and my Chiron return?
- The Chiron sign is where Chiron was when you were born. The Chiron return is when it comes back to that exact degree, usually around age 50. The Chiron return calculator dates it.
- Is Chiron a planet?
- No. Chiron is a centaur, a small icy body discovered in 1977. Astrologers use it as a chart point alongside the planets.

Chiron is computed by the Shymea engine from JPL Horizons osculating orbital elements, observed from Earth with Skyfield on NASA JPL DE442 (tropical zodiac, Placidus houses); the engine’s tests put it within about 0.1° for 1950 to 2075. Aspects use a 6° orb (4° for the sextile). Readings are educational, not medical, legal or financial advice. See the editorial policy.
