planetoid

(minor planet)
(an asteroid or physically similar body)

The term planetoid is generally used to mean a minor planet, i.e., a solar system body not a moon or (major) planet, or a comet and larger than a meteoroid. It serves as an alternative to the term asteroid, specifically implying a generalization to include bodies outside the asteroid belt.

The term may be more commonly used in the abstract: in discussions of planet formation, of likely similar objects orbiting other stars (harder to detect for being smaller) or in the past, such as a solar system body theorized to have broken up long ago.
