2873 Binzel, provisional designation 1982 FR, is a stony Florian asteroid and binary system from the inner regions of the asteroid belt, approximately 6.5 kilometers in diameter. It was discovered on 28 March 1982, by American astronomer Edward Bowell at the Anderson Mesa Station in Flagstaff, Arizona. [10] The asteroid was named after astronomer Richard Binzel. [2] Its 1.6-kilometer minor-planet moon was discovered in 2019. [5]
Binzel is a member of the Flora family ( 402 ), a giant asteroid family and the largest family of stony asteroids in the main-belt. [3] [4] [11] : 23 It orbits the Sun in the inner main belt at a distance of 1.9–2.6 AU once every 3 years and 5 months (1,234 days). Its orbit has an eccentricity of 0.16 and an inclination of 6° with respect to the ecliptic. [1]
The body's observation arc begins with its identification as 1935 KH at the Johannesburg Observatory in 1935, almost 47 years prior to its official discovery observation at Anderson Mesa. [10]
In the SMASS classification, Binzel is a Sq-subtype, which transition from the common stony S-type asteroids to the less common Q-types. [1]
In September 2010, a rotational lightcurve of Binzel was obtained from photometric observations in the R-band by astronomers at the Palomar Transient Factory in California. Lightcurve analysis gave a rotation period of 11.560 hours with a brightness variation of 0.14 magnitude ( U=2 ). [8]
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Binzel measures 6.426 and 7.011 kilometers in diameter and its surface has an albedo of 0.2307 and 0.272, respectively. [6] [7]
The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, the largest member and namesake of the Flora family – and calculates a diameter of 6.48 kilometers based on an absolute magnitude of 13.11. [3]
This minor planet was named after American astronomer Richard Binzel (born 1958) of the University of Texas at Austin. During the 1980s, Binzel has been a prolific photometrist, obtaining a large number of rotational lightcurves of main-belt asteroids. The official naming citation was prepared by Alan W. Harris and published by the Minor Planet Center on 8 November 1984 ( M.P.C. 9215). [2] [12]
