Your inner flatshare
Your birth chart has many planets, not just the Sun. Each one colours a different part of you. Find out which ones matter most for you.

Your birth chart is a flatshare. The Sun is just one flatmate. Each planet is a different part of you, and each one has a specific job to do. Mercury is how you think. Mars is how you act. Venus is what you love. The zodiac sign a planet is in simply describes its personal style. Many people find these other planets describe them better than their Sun sign. See if that's true for you.

Planet sign calculator: where your planets sit
Your star sign is only the sign of the Sun. When you were born, ten bodies stood somewhere in the zodiac, and each colours a different part of you: Mercury your thinking and talking, Venus your taste, Mars your drive, Saturn your duties. Because the planets travel at different speeds, two people with the same Sun sign can have completely different planet signs. The table shows where the planets are today and how long each one typically stays in a sign.

The ten planets today and their pace
| Planet | Sign today | Stays per sign |
|---|---|---|
| Sun | Scorpio | about 30 days |
| Moon | Scorpio | about 2.5 days |
| Mercury | Scorpio | 2–9 weeks |
| Venus | Libra | 3–5 weeks, up to 4 months |
| Mars | Leo | about 6–7 weeks, up to 7 months |
| Jupiter | Leo | about 1 year |
| Saturn | Aries | about 2.5 years |
| Uranus | Gemini | about 7 years |
| Neptune | Aries | about 14 years |
| Pluto | Aquarius | 12–31 years |
Personal, social, generational
- Personal planets: Sun, Moon, Mercury, Venus, Mars. They change fast and set you apart from people born only weeks earlier.
- Social planets: Jupiter and Saturn. You share their sign with everyone born in the same or neighbouring years.
- Generational planets: Uranus, Neptune, Pluto. Their sign describes an age group. They only get personal through house and aspects. Example: Neptune by birth year.
Try this after calculating: read your Mercury first and your Sun after. Tomorrow, notice how you word a difficult message. The sign is only half the answer: the house calculator shows which house each planet is in, the aspect calculator how they relate. The Moon and Venus have their own tools: Moon sign and Venus sign. Your birth chart shows the whole picture.
Which planet signs are the most common?
The slower a planet, the more unevenly it spreads. The Sun sits between 8.1% and 8.6% in all twelve signs. Pluto was in Leo at 25.1% of all birth moments from 1940 to 2009, and 6 signs do not occur for him in these birth years at all.
The reason is the orbit time. The Sun and Mercury go round the zodiac every year, Mars in just under two, Jupiter in twelve, Saturn in 29.5, Uranus in 84 and Pluto in 248 years. Over 70 years the fast ones even out; the slow ones shape whole generations. Saturn manages just under two and a half rounds, so Virgo leads with 9.9% and Aries trails with 7%.

| Planet | Most common | Least common |
|---|---|---|
| Sun | Cancer 8.6% | Capricorn 8.1% |
| Mercury | Scorpio 9.1% | Taurus 7.5% |
| Mars | Cancer 10% | Aquarius 6.4% |
| Jupiter | Libra 9.3% | Pisces 7% |
| Saturn | Virgo 9.9% | Aries 7% |
| Uranus | Aquarius 10.9% | 1 signs 0% |
| Pluto | Leo 25.1% | 6 signs 0% |
Counted with the Swiss Ephemeris: every moment from 1940 to 2009 at three-hour steps, each counted equally (not official birth records). Stays from a daily scan 1900–2100, from the first entry to the final change of sign.
Planet signs: frequently asked questions
- What's the difference from my star sign?
- Your "star sign" is only your Sun sign. Every other planet sits in a sign as well. Your Mercury sign, for example, shows how you think, and your Mars sign what drives you.
- Do I need my birth time?
- No. A planet's sign depends only on the date. You only need the time for houses and the ascendant.
- How accurate is the calculation?
- Accurate to the arc-second. We calculate with the Swiss Ephemeris, which professional astrology software also uses as its standard.
