Planet Meanings

Overview

Astrology assigns symbolic meanings to the Sun, Moon and planets. These attributions have a documented history reaching back to Mesopotamian deity associations, and they are entirely distinct from the physical astronomy of the same bodies.

• Astrology's 'planets' include the Sun and Moon, which astronomy does not classify as planets.
• The classical set is the seven bodies visible without a telescope.
• Uranus, Neptune and Pluto were added after discovery, and traditional astrologers often exclude them.
• The attributions descend from deity associations that predate Greek astrology.

The classical seven

Before the telescope, seven bodies were seen to move against the fixed stars: the Sun, the Moon, Mercury, Venus, Mars, Jupiter and Saturn. Astrological tradition treats all seven as 'planets' in its own sense of the word — moving bodies — which is why the Sun and Moon appear in that list despite not being planets astronomically.

That same seven produced the seven-day week, with each day named for one of them, a naming scheme still visible across many European languages. The tradition and the calendar share an origin.

Traditional attributions

• Sun — vitality, conscious identity, purpose. Traditionally rules Leo.
• Moon — emotion, instinct, habit, the inner life. Traditionally rules Cancer.
• Mercury — communication, reasoning, exchange. Traditionally rules Gemini and Virgo.
• Venus — attraction, harmony, values, relationship. Traditionally rules Taurus and Libra.
• Mars — drive, assertion, conflict, action. Traditionally rules Aries, and in classical schemes Scorpio.
• Jupiter — expansion, growth, belief, opportunity. Traditionally rules Sagittarius, and classically Pisces.
• Saturn — limitation, structure, discipline, time. Traditionally rules Capricorn, and classically Aquarius.

The modern additions

Uranus (1781), Neptune (1846) and Pluto (1930) were incorporated into Western practice after their discoveries, and modern astrology commonly reassigns rulerships to them — Uranus to Aquarius, Neptune to Pisces, Pluto to Scorpio — displacing the classical rulers.

Traditional and Hellenistic revivalist astrologers frequently reject these reassignments and work with the seven classical bodies alone, arguing that the dignity scheme's internal logic depends on the sevenfold structure. This is a real and unresolved methodological split within the field, and Pluto's 2006 astronomical reclassification as a dwarf planet did not settle it, since astrological usage does not follow the IAU.

Where the meanings came from

The attributions descend from deity associations. Mesopotamian tradition linked each visible planet to a god, Greek practice mapped those onto its own pantheon, and Rome mapped them again onto Latin equivalents — which is why the planets carry Roman names and roughly Roman-flavoured attributes.

Some associations plausibly reflect observation: Mars is visibly red and carries martial attributes; Mercury moves fastest and is associated with the messenger. Others reflect brightness and stateliness rather than any observable property. The physical astronomy — that Mars is a cold desert world with a thin carbon-dioxide atmosphere — is unrelated to the symbolic layer, and Asteria Star keeps the two on separate pages.

Frequently asked

Why does astrology call the Sun and Moon planets?

Because the word originally meant 'wanderer' — a body that moves against the fixed stars. Seven such bodies are visible without a telescope, including the Sun and Moon, and astrological tradition treats all seven together. Astronomy later narrowed the term, but astrology kept the older usage, so its 'planets' and astronomy's are different categories.

Do astrologers use Uranus, Neptune and Pluto?

Many modern Western astrologers do, and assign them rulership of Aquarius, Pisces and Scorpio respectively. Traditional and Hellenistic practitioners frequently do not, working only with the seven classical bodies on the grounds that the dignity system's structure depends on the sevenfold scheme. It is a genuine and ongoing methodological disagreement.

Where do the planetary meanings come from?

From deity associations transmitted through Mesopotamian, Greek and Roman tradition. Each visible planet was linked to a god, and the attributes of that god became the planet's symbolic domain. A few associations plausibly track something observable — Mars's colour, Mercury's speed — but most reflect the inherited mythology rather than any property of the body.
