A planetoid is a small celestial body that orbits the sun, similar to a planet but significantly smaller than a major planet. Planetoids are often called asteroids and can be found primarily in the asteroid belt between Mars and Jupiter. They can vary in size, shape, and composition, with some being rocky and others icy.

Synonyms

asteroid, minor planet, small celestial body

Examples of usage

  • The planetoid Ceres is located in the asteroid belt.
  • Astronomers discovered a new planetoid in the Kuiper Belt.

Etymology

The term 'planetoid' originates from the Greek words 'planetes,' meaning 'wanderer' (referring to the planets), and the suffix '-oid,' which denotes resemblance or likeness. The word began to be used in the early 19th century as astronomers started to discover smaller bodies in the solar system that resembled planets but were far less massive. The study of these celestial objects gained momentum with advancements in telescopes and space exploration technology, leading to a better understanding of the composition and dynamics of planetoids. The classification of planetoids also reflects the broader category of small solar system bodies, which includes comets and meteoroids.
