Named in honor of William F. Bottke, Jr., known for his research on the collisional and dynamical evolution of minor planets. He has also contributed to the study of the origin and evolution of NEAs, in particular by analyzing the formation of doublet craters found on the terrestrial planets.

Dr. Bottke was elected an honorary member of the Royal Astronomical Society of Canada on 2012-06-29.

1781 van Biesbroeck (A906 UB) is a main-belt asteroid discovered on October 17, 1906 by A. Kopff at Heidelberg.

Georges-Achille van Biesbroeck (January 21, 1880 – February 23, 1974) was a Belgian-American astronomer. He worked at observatories in Belgium, Germany and the United States. He specialized in the observation of double stars, asteroids and comets. He is notable for his long career as an observational astronomer.

Discovered by the Indiana Asteroid Program, Goethe Link Observatory, University of Indiana. This program was conceived and directed by F. K. Edmondson; the plates were blinked and measured astrometrically by B. Potter and, following her retirement, by D. Owings; and the photometry was performed under the direction of T. Gehrels. During the years 1947-1967, in which the plates were exposed, a large number of people participated in various aspects of the program.

1422 Stromgrenia (1936 QF)          Discovered 1936-Aug-23 by Reinmuth, K. at Heidelberg

Bengt Georg Daniel Strömgren (21 January 1908 – 4 July 1987) was a Danish astronomer and astrophysicist.

(1123) Shapleya is a main belt asteroid orbiting the Sun. The time it takes to complete one rotation is greater than 20 hours. It was discovered by Grigory Nikolaevich Neujmin on September 21, 1928 at Simeïs. It was named after Harlow Shapley, the American astronomer and director of Harvard Observatory.

Frank Schlesinger (May 11, 1871 New York City – July 10, 1943 Old Lyme, Connecticut) was an American astronomer. His work concentrated on using photographic plates rather than direct visual studies for astronomical research.

Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.

Martin Ryle (1918-1984) was a British astrophysicist who developed the aperture synthesis technique of interferometry and constructed large radio telescopes, using them to discover and catalogue numerous radio sources.

6886 Grote (1942 CG) is a main-belt asteroid discovered on February 11, 1942 by L. Oterma at Turku. It is named for American radio astronomer Grote Reber (b. 1911, d. 2002), pioneer radioastronomer.
