28439 Miguelreyes (provisional designation2000 AM30) is a backgroundasteroid from the central region of theasteroid belt, approximately 3.9 kilometers in diameter. The asteroid was discovered on 3 January 2000, by theLINEAR team atLincoln Lab's ETS in Socorro, New Mexico, United States.[2] It was named for Filipino student Miguel Reyes, a 2011ISEF awardee.
Miguelreyes is a non-family from the main belt'sbackground population. It orbits the Sun in thecentral asteroid belt at a distance of 2.5–3.0 AU once every 4 years and 7 months (1,679 days). Its orbit has aneccentricity of 0.09 and aninclination of 4° with respect to theecliptic.[1]
The asteroid'sobservation arc begins almost 4 years prior to its official discovery observation, with aprecovery taken by theSteward Observatory'sSpacewatch survey at Kitt Peakt in April 1996.[2]
According to the survey carried out by theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer, Miguelreyes measures 3.851 kilometers in diameter and its surface has analbedo of 0.249.[3]
As of 2018, Miguelreyes'sspectral type, as well as itsrotation period and shape remain unknown.[1][4]
Thisminor planet was named in honor of Miguel Arnold Silverio Reyes, a Philippine high-school student from Manila, who was awarded second place in the 2011Intel 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 thePhilippine Science High School in Quezon City, Philippines.[5][6][7]
