    4008 Corbin, provisional designation 1977 BY, is a stony asteroid from the inner regions of the asteroid belt, about 6 kilometers in diameter. It was discovered on 22 January 1977, by staff members of the Felix Aguilar Observatory's Carlos U. Cesco Station (EACUC) at the Leoncito Astronomical Complex in Argentina.[5]

    The stony S-type asteroid is a member of the Phocaea family, a group of asteroids with similar orbital characteristics. It orbits the Sun at a distance of 1.9–2.9 AU once every 3 years and 7 months (1,324 days). Its orbit shows an eccentricity of 0.21 and an inclination of 26 degrees from the plane of the ecliptic.[1]

    A photometric light-curve analysis by Czech astronomer Petr Pravec at Ondřejov Observatory in 2010 rendered a well-defined rotation period of 6.203±0.001 hours with a brightness amplitude of 0.12 in magnitude.[lower-alpha 1] According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid has an albedo of 0.28 and a diameter of 6.0 kilometers, while the Collaborative Asteroid Lightcurve Link (CALL) assumes a somewhat lower albedo of 0.23 and calculates a correspondingly larger diameter of 6.4 kilometers.[3][4]

    The minor planet was named in honor of American astronomer Thomas E. Corbin, head of the Meridian Circle Division at USNO, and his wife, Brenda Groves Corbin, who was the Observatory’s librarian and one of the most renowned astronomical librarians in the world. Serving early in his career as astronomer-in-charge of the Observatory’s southern station in Argentina, Tom Corbin has since been responsible for several important astrometric programs, including the Astrographic Catalogue Reference Stars catalogue. Brenda Corbin is known for her work in the Special Libraries Association, in IAU's Commission 5 Working Group on Nomenclature, and for her enthusiasm in tracking down copies of rare works.[2]
