The planets in astrology

Ten planets, the North Node and Chiron: what each one means in your birth chart and how it changes through the twelve signs and houses.

What the planets mean in a birth chart

A birth chart is a snapshot of the sky at the moment you were born: where the Sun, the Moon and the planets stood, seen from your place of birth. Astrology reads each of these bodies as a different part of you — the Sun as your core identity, the Moon as your emotional needs, Mercury as the way you think and talk, Venus as what you love and value, Mars as your drive. A planet describes a function, something you do; the sign it sits in describes how you do it, and the house it falls in shows where in life it shows up most.

The planets move at very different speeds, and that changes how personal they are. The Moon crosses a whole sign in about two and a half days, so it can differ even between people born a few days apart. Mercury, Venus and Mars change sign every few weeks or months. Jupiter spends about a year in each sign and Saturn about two and a half years, which is why classmates often share them. Uranus, Neptune and Pluto stay in one sign for seven to more than twenty years, so their sign speaks about a generation, while their house position is what makes them personal.

Two more points complete the picture. The North Node is not a body but the place where the Moon's orbit crosses the Sun's apparent path; astrologers read it as a direction of growth. Chiron is a small body orbiting between Saturn and Uranus, associated with sensitive spots that can turn into wisdom. On each planet's page you will find its meaning, its rulership and dignities, and short interpretations for all twelve signs and houses — use them as prompts for self-reflection, not as fixed predictions.

Planets in astrology

Four families of planets

Personal planets

The Sun, Moon, Mercury, Venus and Mars move quickly, so their signs and houses are highly individual. They describe your identity, feelings, mind, affections and drive.

  • Sun

    Around the zodiac: 1 year
    In each sign: about 30 days
    The Sun shows your core identity — the essential self you are growing into and the kinds of activity that make you feel most alive. Its sign and house describe where you shine, how you use your will and what gives your life a sense of purpose.
  • Moon

    Around the zodiac: 27.3 days
    In each sign: about 2.5 days
    The Moon describes your emotional nature — what you need to feel safe, how you react on instinct and how you comfort yourself and others. It speaks of your inner world, your habits and the kind of care that truly nourishes you.
  • Mercury

    Around the zodiac: about 1 year
    In each sign: 2 weeks to 2 months
    Mercury governs how you think, speak, learn and process information. Its placement reveals your mental style — quick or careful, logical or intuitive — and how you connect with people through words.
  • Venus

    Around the zodiac: about 1 year
    In each sign: about 4 weeks; up to 4 months when retrograde
    Venus shows what you love and how you love — your taste, your way of showing affection and what brings you pleasure. It also reflects your values, your sense of beauty and how you create harmony in relationships.
  • Mars

    Around the zodiac: about 2 years
    In each sign: 6–8 weeks; up to about 6 months when retrograde
    Mars is your engine: it shows how you go after what you want, how you stand up for yourself and how you handle conflict. Its placement describes your energy, your desires and the particular kind of courage you bring to challenges.

Social planets

Jupiter and Saturn link the personal and the collective: growth and opportunity on one side, structure and responsibility on the other. Each spends one to three years in a sign.

  • Jupiter

    Around the zodiac: about 12 years
    In each sign: about 1 year
    Jupiter shows where you grow most easily and where life tends to open doors when you meet it with trust. It points to your philosophy, your generosity and the areas where learning and widening your horizons come naturally.
  • Saturn

    Around the zodiac: about 29.5 years
    In each sign: about 2.5 years
    Saturn marks where you are asked to build patiently, take responsibility and develop real mastery over time. What feels slow or demanding here often becomes, with steady effort, one of your most solid strengths.

Outer planets

Uranus, Neptune and Pluto move slowly and mark generations. In a personal chart, their house and their aspects to your personal planets matter most.

  • Uranus

    Around the zodiac: about 84 years
    In each sign: about 7 years
    Uranus shows where you need freedom, where you break with convention and where sudden insights shake things up. It describes your unique spark and the areas of life where you naturally do things your own way.
  • Neptune

    Around the zodiac: about 165 years
    In each sign: about 14 years
    Neptune is the planet of imagination, compassion and the longing for something larger than everyday life. Its placement shows where inspiration and intuition flow most freely — and where it helps to check that your ideals still match reality.
  • Pluto

    Around the zodiac: about 248 years
    In each sign: about 12 to 31 years
    Pluto shows where you experience life at its most intense and where deep transformation becomes possible. It points to your inner power, your capacity for renewal and the areas where growth asks you to let go of the old.

The Node and Chiron

The North Node and Chiron are not planets in the classical sense, but they are widely used: the Node as a direction of growth, Chiron as a sensitive spot that can become a source of wisdom.

  • North Node

    Around the zodiac: about 18.6 years (moving backwards)
    In each sign: about 18 months
    The North Node points to the qualities you are growing toward in your life — unfamiliar territory that can feel awkward at first but becomes deeply fulfilling over time. It works as a pair with the South Node, which shows the comfortable skills you already have and can build upon.
  • Chiron

    Around the zodiac: about 50 years
    In each sign: about 1.5 to 8 years
    Chiron marks a tender spot in your story — an area where you may once have felt out of place or unsure — and shows how that very experience can become a source of wisdom. As you make peace with it, you often discover a real gift for supporting others who face the same struggle.

Beyond one placement

See your whole sky

One placement is one thread. Your birth chart shows all ten planets, the Ascendant and the twelve houses working together — calculated to the minute, free and without signing up.

Astrology here is a language for self-reflection, not a prediction, diagnosis or advice. A single placement describes a tendency; your whole birth chart always tells a more personal story.
