2301 Whitford, provisional designation, is a background asteroid from the outer regions of the asteroid belt, approximately 17abbr=offNaNabbr=off in diameter. It was discovered on 20 November 1965, by astronomers of the Indiana Asteroid Program at Goethe Link Observatory in the United States. The asteroid was named for American physicist and astronomer Albert Whitford. The uncommon L-type asteroid has a rotation period of 14.3 hours.
Whitford is a non-family asteroid from the main belt's background population. It orbits the Sun in the outer main-belt at a distance of 2.5–3.9 AU once every 5 years and 8 months (2,073 days; semi-major axis of 3.18 AU). Its orbit has an eccentricity of 0.21 and an inclination of 12° with respect to the ecliptic.
The asteroid was first observed as at Lowell Observatory in October 1931. The body's observation arc begins ten years prior to its official discovery observation with its observation as at Goethe Link Observatory in January 1955.
Whitford has been characterized as an uncommon L-type asteroid by Pan-STARRS photometric survey. It is also characterized as a common S-type asteroid in the SDSS-MFB (Masi Foglia Binzel) taxonomy.
In April 2012, a rotational lightcurve of Whitford 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 14.275 hours with a brightness amplitude of 0.35 magnitude, superseding a previous measurement of 27.1 hours .
According to the surveys carried out by the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Whitford measures between 17.40 and 19.47 kilometers in diameter and its surface has an albedo between 0.223 and 0.240.
The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 16.56 kilometers based on an absolute magnitude of 11.27.
This minor planet was named after American physicist and astronomer Albert Whitford (1905–2002), who was a pioneer in photoelectric photometry. Whitford was also a director at the Washburn and Lick observatories, as well as a former president of the American Astronomical Society. The official naming citation was published by the Minor Planet Center on 20 December 1983 .
