36369

36369 is a numbered minor planet of the inner main asteroid belt. It was discovered on 3 September 1998 by the Lincoln Near‑Earth Asteroid Research (LINEAR) survey at the Socorro, New Mexico observatory. The provisional designation assigned at the time of its discovery was 1998 SM57. The asteroid was subsequently named after Japanese astronomer Masahide Ohno, who contributed to the study of near‑Earth objects and the calibration of photometric data.

Its orbit has a semi‑major axis of 2.53 astronomical units, an eccentricity of 0.08 and an inclination of 12°. The orbital period is approximately 4.0 years (1,468 days). Photometric observations indicate a rotation period of about 4.6 hours, although the amplitude of its lightcurve suggests a nearly spheroidal shape. The absolute magnitude of the asteroid is 14.8, giving an estimated diameter of 4–5 kilometres, assuming a typical albedo of 0.20.

36369 has been observed repeatedly by the survey's automated telescopes and has been included in data sets used to constrain the distribution of sizes and albedos in the inner belt. No close approaches to Earth have been recorded for the next several centuries, and the asteroid is not considered a potential impactor. The minor planet is catalogued in several astronomical databases including the Jet Propulsion Laboratory’s Small‑Body Database and the Minor Planet Center.
