Why does astrology call the Sun and Moon planets?

The Sun is a star and the Moon is a natural satellite. Learn why older Western astrology still groups them with five planets.

You may see the Sun and Moon among the seven “traditional planets” in an astrology guide. That is an older chart label, not their scientific classification.

The older group has seven names

Traditional Western astrology groups the Sun, Moon, Mercury, Venus, Mars, Jupiter, and Saturn together. Early skywatchers followed these bright bodies as they changed position in our sky. The Sun and Moon stand out as bright objects in the sky.

Astronomy names the objects differently

The Sun is a star. The Moon is Earth’s natural satellite. Mercury, Venus, Mars, Jupiter, and Saturn are planets in modern astronomy. The old chart grouping does not change what these objects are.

Read the label as chart vocabulary

When you read “seven traditional planets,” count the Sun and Moon in that seven. Their names tell you which positions an astrologer is discussing. The grouping itself says nothing certain about a person or an event.

A few common questions

Are the Sun and Moon planets in astronomy?

No. Astronomy classifies the Sun as a star and the Moon as Earth’s natural satellite. “Seven traditional planets” is an older astrological label.
