500749

500749 is a numbered minor planet of the asteroid belt. The body was first observed on 13 September 2010 by the Pan‑Starrs 1 survey at Haleakala Observatory, Hawaii, using a 1.8‑meter telescope. Its discovery was announced by the Minor Planet Center on 8 December 2010 and subsequently it received its permanent number, 500749, following the confirmation of its orbit.

The asteroid is classified as a typical S‑type in the spectral taxonomy derived from visible photometry, indicating a silicate‑rich surface composition common among inner‑belt objects. 500749’s orbit around the Sun is well‑determined, with a semi‑major axis of 2.34 astronomical units, an eccentricity of 0.14 and an inclination of 4.2 degrees relative to the ecliptic. Its orbital period is approximately 3.58 years. The object has an estimated diameter of 4.6 kilometres, derived from the absolute magnitude H = 15.7 and an assumed albedo of 0.20.

No rotation period, pole orientation or shape model has yet been published for 500749, and it has not been assigned a formal name. It is listed in the JPL Small‑Body Database and on the Minor Planet Center’s “Discovery Circumstances” page for numbered minor planets.

Although there is currently limited observational data beyond its orbital elements, 500749 contributes to the statistical studies of the size, composition and dynamical evolution of the asteroid belt, particularly in the context of the large population of bodies numbered beyond five hundred thousand.
