1414 Jérôme, provisional designation1937 CE, is a carbonaceous Dorianasteroid from the central region of theasteroid belt, approximately 16 kilometers in diameter. It was discovered on 12 February 1937 by, French astronomerLouis Boyer atAlgiers Observatory, Algeria, in northern Africa, and named after his father Jérôme Boyer.[2][6]
Jérôme is a member of theDora family (FIN: 512), a well-established centralasteroid family of more than 1,200 carbonaceous asteroids. The family's namesake is668 Dora. It is alternatively known as the "Zhongolovich family", named after its presumably largest member1734 Zhongolovich. The Dora family may also contain a subfamily.[3][7]: 13, 23
Jérôme orbits the Sun in themiddle main-belt at a distance of 2.3–3.2 AU once every 4 years and 8 months (1,697 days). Its orbit has aneccentricity of 0.16 and aninclination of 9° with respect to theecliptic.[1] The body'sobservation arc starts with its official discovery observation, as noprecoveries were taken and no prior identifications were made.[6]
Jérôme is a darkC-type asteroid, classified as a hydrated Ch-subtype in theSMASS classification scheme.[1]
According to the surveys carried out by the Infrared Astronomical SatelliteIRAS and NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission,Jérôme measures 15.1 and 17.2 kilometers in diameter, and its surface has analbedo of 0.065 and 0.054, respectively.[4][5] It has an absolutemagnitude of 13.1.
As of 2017,Jérôme'srotation period, spin axis and shape remains unknown.[1][8]
Thisminor planet was named by the discoverer in honour of his father, Jérôme Boyer.[2] Naming citation was first mentioned inThe Names of the Minor Planets byPaul Herget in 1955 (H 128).[2]
