(1983 WJ)

(at the anderson mesa astronomical observatory)
(arizona)

(a minor planet is an astronomical object in direct orbit around the sun that is neither a “planet” nor exclusively classified as a “comet”)
(“minor planets” can be ‘dwarf planets’, ‘asteroids’, ‘trojans’, ‘centaurs’, ‘Kuiper belt objects’, and other trans-Neptunian objects)
(the orbits of 692,604 minor planets were archived at the “Minor Planet Center” by 2015)
(the first minor planet to be discovered was ‘Ceres’ in 1801)
(the term minor planet has been used since the 19th century to describe these objects)
(the term planetoid has also been used, especially for larger (planetary) objects such as those the “International Astronomical Union” (IAU) has called ‘dwarf planets’ since 2006)
(historically, the terms asteroid, minor planet, and planetoid have been more or less synonymous)
(this terminology has become more complicated by the discovery of numerous ‘minor planets’ beyond the orbit of ‘Jupiter’, especially trans-Neptunian objects that are generally not considered ‘asteroids’)
(‘minor planets’ seen releasing gas may be dually classified as a ‘comet’)
(before 2006, the IAU had officially used the term “minor planet”)
(during its 2006 meeting, the IAU reclassified ‘minor planets’ and ‘comets’ into ‘dwarf planets’ and “small Solar System bodies” (SSSB))
(objects are called ‘dwarf planets’ if their self-gravity is sufficient to achieve ‘hydrostatic equilibrium’ and form an ‘ellipsoidal’ shape)
(all other ‘minor planets’ and ‘comets’ are called “small solar system bodies”)
(the IAU stated that the term minor planet may still be used, but the term small Solar system body will be preferred)
.
(however, for purposes of numbering and naming, the traditional distinction between ‘minor planet’ and ‘comet’ is still used)
