30718 Records, provisional designation 1955 RB1, is a dark asteroid from the middle region of the asteroid belt, approximately 9 kilometers in diameter. It was discovered on 14 September 1955, by Indiana University at the U.S. Goethe Link Observatory in Brooklyn, Indiana, during the Indiana Asteroid Program.[2] It was the program's final discovery, in terms of numbering and naming.[3]
The asteroid orbits the Sun at a distance of 1.9–3.6 AU once every 4 years and 7 months (1,679 days). Its orbit has an eccentricity of 0.32 and an inclination of 5° with respect to the ecliptic.[1] As no precoveries were taken, the asteroid's observation arc begins with its discovery observation in 1955.[2] According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid measures 9.219±0.022 kilometers in diameter and its surface has a low albedo of 0.066 of 0.066±0.010.[4] As of 2016, the body's spectral type, as well as its rotation period and shape remain unknown.[1]
The name honors Brenda Records (b. 1946), who served as office manager for the Indiana University Department of Astronomy for over 20 years.[2][3] Naming citation was published on 24 November 2007 (M.P.C. 61269).[5]
