minor planet

Small solar orbiter

A minor planet is a celestial body that orbits the Sun but isn't classified as a planet or comet.

The term encompasses asteroids, dwarf planets like Pluto and Ceres, and other small rocky or icy objects.

Astronomers catalogued thousands of minor planets in the asteroid belt between Mars and Jupiter before the term gave way to more specific categories.
