30718 Records (provisional designation 1955 RB1) is a dark background asteroid from the central region of the asteroid belt, approximately 9 kilometers in diameter. It was discovered on 14 September 1955, by Indiana University's Indiana Asteroid Program at its Goethe Link Observatory near Brooklyn, Indiana, United States.[2] It was the program's final discovery and was named after IU's astronomy staff member Brenda Records.[3]
Records is a non-family from the main belt's background population. It orbits the Sun in the central asteroid belt 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 body's observation arc begins with its official discovery observation in 1955.[2]
Physical characteristics
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Records measures 9.219 kilometers in diameter and its surface has a low albedo of 0.066.[4]
As of 2018, the asteroid's spectral type, as well as its rotation period and shape remain unknown.[1][5]
