100239

100239 is the numerical designation assigned to a minor planet in the Solar System. It is listed in the Minor Planet Center's catalog of numbered minor planets, a database maintained by the International Astronomical Union. The assignment of a number indicates that the object's orbit has been observed sufficiently to determine a reliable trajectory. After numbering, the object may be given a name by its discoverers, though many minor planets remain unnamed.

Discovery details such as the date of discovery, discovering observatory or individual, and the provisional designation are recorded in the MPC database. Orbital elements and ephemerides for 100239 are also published in the MPC and in the JPL Small-Body Database, allowing predictions of its position over time.

Physical characteristics for numbered minor planets vary in precision. Some objects have measured diameters, albedos, rotations, or spectral classifications, while others have only rough estimates derived from infrared surveys or assumptions based on brightness.

As with other numbered minor planets, 100239's precise classification, orbit, and any named designation can be found in up-to-date astronomical databases. See also the list of minor planets, 100001–100500, and the pages for the Minor Planet Center and the JPL Small-Body Database for further details.
