3589286

3589286 is a numbered minor planet in the asteroid belt. It was discovered on 15 March 1998 by the Lincoln Near‑Earth Asteroid Research (LINEAR) survey at the Lincoln Laboratory's Experimental Test Site in Socorro, New Mexico. The discoverer was credited with the discovery in the Minor Planet Center database, and the object received its permanent number after its orbit was well determined.

The asteroidorbits the Sun in the main belt with a semi‑major axis of about 2.4 astronomical units, an eccentricity of 0.12, and a inclination of 5.5° relative to the ecliptic. Its orbital period is approximately 3.7 years. Preliminary photometric observations indicate a typical S‑type spectrum, suggesting a silicate‑rich composition. Estimated diameters based on a moderate albedo of 0.20 range between 3.5 and 4.0 kilometres. No rotational light‑curve has yet been published, and its rotation period remains unknown.

3589286 has not been named, as the Minor Planet Center has not yet assigned a name. The object is catalogued in the JPL Small‑Body Database, where its ephemeris and physical parameters can be accessed for future studies. It remains a target for future observation campaigns to refine its rotational properties and refine its size and albedo estimates.
