113444

113444 is a numbered asteroid that resides in the main asteroid belt between Mars and Jupiter. It was first observed on 10 September 2003 by the Lincoln Near‑Earth Asteroid Research (LINEAR) survey at the Whipple Observatory in Arizona. The asteroid initially received the provisional designation 2003 QF561 before its orbit was confirmed and it was assigned the permanent number 113444 by the Minor Planet Center.

The object's orbital parameters place it firmly in the central region of the main belt. Its semimajor axis measures approximately 2.43 astronomical units (AU), with a perihelion distance of about 1.99 AU and an aphelion of roughly 2.87 AU. The orbital period is around 3.79 years (approximately 1,383 days). Its orbit is moderately elliptical, with an eccentricity of about 0.184, and it is inclined by roughly 10.6 degrees relative to the ecliptic plane. Because its inclination and eccentricity are typical for asteroids in this region, 113444 is likely a background asteroid rather than a member of a recognized dynamical family.

Physical observations indicate that 113444 has a low albedo, suggesting a dark, carbonaceous surface composition. Photometric measurements give a rotation period of roughly 7.6 hours and a light‑curve amplitude of about 0.3 magnitudes, implying a modestly elongated shape. Based on its spectral characteristics and size estimates from infrared surveys, the diameter is approximately 7.5 kilometers, though the precise value depends on the assumed albedo.

No official name has been assigned to 113444 to date, so it remains identified solely by its number and provisional designation. The Minor Planet Center and databases such as JPL's Small‑Body Database provide the most up‑to‑date orbital and physical information.
