A minor planet is a general term for small-bodies in our solar system not classified as comets. Asteroids and trans-Neptunian objects are considered minor planets. These objects may also be called planetesimals.
We use the term "asteroid" to imply "minor planet" on this web-site.
NOTE:
The list of defined terms to the left is by no means exhaustive with
respect to the general subject of solar system dynamics.
The terms listed are thought to be those more commonly used on our site
and thus appropriate for inclusion on this page.
