Understanding the Planets in Astrology

In astrology the “planets” include the Sun and Moon (the two luminaries) alongside Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. Each one represents a distinct psychological function: the Sun is your core identity, the Moon your emotional needs, Mercury how you think and communicate, Venus how you love and what you value, and Mars how you act and assert yourself.

The planets are grouped by speed. The personal planets — Sun, Moon, Mercury, Venus and Mars — move quickly and shape your individual character. The social planets, Jupiter and Saturn, govern growth, ambition and responsibility. The outer planets — Uranus, Neptune and Pluto — move slowly and mark generational themes of change, dissolution and transformation.

A planet’s meaning is coloured by the sign it occupies (its style), the house it falls in (its arena of life) and the aspects it forms with other planets. Use the cards above to explore each planet in depth, then calculate your natal chart to see exactly where they sit in your own horoscope.

Frequently asked questions

How many planets are used in astrology?
Western astrology uses ten “planets”: the Sun and Moon (technically luminaries) plus Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. Many astrologers also include points such as the lunar nodes and Chiron.
What is the difference between personal, social and outer planets?
Personal planets (Sun, Moon, Mercury, Venus, Mars) move quickly and define individual personality. Social planets (Jupiter, Saturn) shape how you engage with society. Outer planets (Uranus, Neptune, Pluto) move slowly and describe long, generational shifts.
What does a planet’s sign and house mean?
The sign shows the style in which a planet expresses itself, while the house shows the area of life where that energy plays out. Mars in Aries acts boldly; Mars in the 10th house directs that drive toward career.
Why is the Sun considered a planet in astrology?
Astrology predates modern astronomy and uses “planet” for any major moving body seen from Earth. The Sun and Moon are more precisely called luminaries, but they are interpreted alongside the planets.
