Planetary bodies or celestial bodies are all of the movable objects in the heavens, mostly seen, and some unseen.
In classical/traditional astrology, the visible planetary bodies are taken into account. These are typically referred to by astrologers as “planets”.
We have the Sun and Moon, which are technically luminaries (but that is just a classification). As well as Mercury, Venus, Mars, Jupiter, and Saturn.
In modern astrology, the outer planets are also included, they are, Uranus, Neptune and Pluto. (Pluto has been demoted as a planet in astronomy circles but not astrology circles).
Other planetary bodies that might be loosely referred to or treated as planets would be other astrologically significant points in the heavens such as, Hermetic Lots, Lunar Nodes, and certain Asteroids such as Chiron, Eris, Vesta, and Pallas Athene.
