18880 Toddblumberg, provisional designation 1999 XM166, is an asteroid from the outer region of the asteroid belt, approximately 4 kilometers in diameter. It was discovered on 10 December 1999, by LINEAR at Lincoln Laboratory's Experimental Test Site, near Socorro, New Mexico.[4]
The asteroid orbits the Sun at a distance of 2.6–3.8 AU once every 5 years and 9 months (2,096 days). Its orbit has an eccentricity of 0.18 and an inclination of 10° with respect to the ecliptic.[1] The first precovery was taken at Palomar Observatory (DSS) in 1953, extending the asteroid's observation arc by 46 years prior to its discovery.[4]
Although discovered by LINEAR, 18880 Toddblumberg is not a near-Earth asteroid. Its closest approach to the Sun (perihelion) is about double the maximum distance of 1.3 AU that qualifies an asteroid as "near-Earth".[5] According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Toddblumberg measures 4.3 kilometers in diameter and its surface has an albedo of 0.265.[3] As of 2016, the bodyŝ spectral type as well as its rotation period remain unknown.
This minor planet was named for Todd James Blumberg (b. 1984), a student at the Plano Senior High School in Plano, Texas, who won the Intel International Science and Engineering Fair (ISEF) award for his microbiology project in 2003.[2][6] Since 2001, hundreds of secondary school students who have won awards at science fairs have had asteroids named after them.[7][8] Naming citation was published on 30 August 2004 (M.P.C. 52648).[9]
