Some asteroids can be seen with the naked eye, such as Ceres (), Pallas () and Vesta (), but were not recognized as planetary, and perhaps not even noticed, until the early 1800s. In the early 1800s, 4 asteroids were scientifically recognized as planets, Ceres, Pallas, Juno () and Vesta. They qualify as minor planets by some definitions. Although asteroids have been known to both astronomers and astrologers for more than 200 years, they are often ignored by astrologers. The tradition of some astrologers casting minor planets originates with these four asteroids.

Since the 1970's,and the discovery of Chiron (), some astrologers have been casting the new "planet", although astronomers consider it a comet.

In the 21st century several new planet-sized bodies, including Sedna, Quaoar, and Eris, have been discovered but not yet incorporated into mainstream astrological predictions, although some more avant-garde groups attempt to incorporate them see Karmastrology.com.

Comets and novae have been observed and discussed for several thousand years. Comets in particular were portents of great interest to ancient people and given various astrological interpretations. Comets are not planets but they are planetary bodies. Both phenomena are rarely visible to the naked-eye, and are ignored by most modern astrologers.
