(6494) 1992 NM is a main-belt minor planet. A minor planet is an
astronomical object in direct orbit around the Sun that is neither
a dominant planet nor a comet, and thus includes the dwarf planets.
The orbital categories of minor planets are the asteroids, trojans,
centaurs, Kuiper belt objects, and other trans-Neptunian objects.
The first minor planet discovered was Ceres in 1801. The orbits of
more than 540,000 objects have been archived at the Minor Planet
Center. The term "minor planet" has been used since the
19th century to describe these objects.
