582899

582899 is a numbered minor planet located in the outer region of the main asteroid belt. It was discovered on 9 March 2014 by the Pan-STARRS survey at Haleakala Observatory, Hawaii. The discovery was confirmed by follow‑up observations from the Mount Lemmon Survey in Arizona. As of the most recent updates from the Minor Planet Center, the object has not yet been assigned a formal name and is referred to by its provisional designation.

In its current orbit, 582899 has a semi‑major axis of approximately 3.16 astronomical units, placing it in the outer main belt beyond the 3:1 Kirkwood gap. Its orbit exhibits a moderate eccentricity of 0.22 and a low inclination of 5.6 degrees relative to the ecliptic. Its orbital period is roughly 5.6 years. These parameters classify the object as a typical background asteroid, with no known family association.

The absolute magnitude of 582899 is H = 15.9, suggesting a diameter in the range of 4 to 7 kilometers, depending on albedo assumptions. Photometric observations from the Lowell Observatory indicate a rotation period of about 6.3 hours with a lightcurve amplitude of 0.1 magnitude, implying a relatively spherical shape. Spectroscopic studies are limited, but the available data are consistent with a C‑type carbonaceous composition, common among outer belt asteroids.

Because 582899 has not yet been studied in depth, many of its physical properties—including precise albedo, mass, and potential binary nature—remain uncertain. Future spectroscopic and radar observations may refine its classification and contribute to a better understanding of the dynamical processes shaping the outer main belt.
