28439 Miguelreyes, provisional designation 2000 AM30, is an asteroid from the middle region of the asteroid belt, approximately 3.9 kilometers in diameter. It was discovered on 3 January 2000, by the U.S. Lincoln Near-Earth Asteroid Research (LINEAR) at Lincoln Lab's ETS in Socorro, New Mexico.[3]
The asteroid orbits the Sun at a distance of 2.5–3.0 AU once every 4 years and 7 months (1,679 days). Its orbit has an eccentricity of 0.09 and an inclination of 4° with respect to the ecliptic.[1] The first precovery was taken at Steward Observatory (Spacewatch) in 1996, extending the asteroid's observation arc by 4 years prior to its discovery.[3]
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid measures 3.851±0.145 kilometers in diameter and its surface has an albedo of 0.249±0.071.[2] As of 2016, the body's spectral type, as well as its rotation period and shape remain unknown.[1]
The minor planet is named in honor of Miguel Arnold Silverio Reyes, a Philippine high-school student from Manila, who was awarded second place in the 2011 Intel International Science and Engineering Fair for his materials and bioengineering project entitled "Synthesis and Characterization of Composite Plastics from Thermoplastic Starch and Nano-sized Calcium Phosphate for Film Packaging". His project sought alternatives, such as cornstarch, in making biodegradable plastic for film packaging. He attended the Philippine Science High School in Quezon City, Philippines.[4][5][6]
