1333 Cevenola, provisional designation1934 DA, is abinary Eunomianasteroid from theasteroid belt, approximately 15 kilometers in diameter. It was discovered on 20 February 1934, by French astronomerOdette Bancilhon atAlgiers Observatory, Algeria in Northern Africa.[14] It was named after the French mountain-rangeCévennes,[2] via theOccitan feminine adjective/demonymcevenòla (cévenole in French).
TheS-type asteroid is a member of theEunomia family.[3] More specifically, it is estimated to have a Sqspectral type, which would also agree with its family classification.[13] It orbits the Sun at a distance of 2.3–3.0 AU once every 4 years and 3 months (1,560 days). Its orbit has aneccentricity of 0.13 and aninclination of 15° with respect to theecliptic.[1] As noprecoveries were taken, and no prior identifications were made, the body'sobservation arc begins with its official discovery observation.[14]

Photometriclightcurve observations gave a well determinedrotation period of 4.88 hours with a brightness variation between 0.57 and 1.1magnitude (U=3/3/3/3/3).[4][9][10][11][12] The asteroid has a geometric albedo of 0.21, as measured by the Japanese Infrared Satellite,Akari, and bySpitzer's Infrared Spectrograph (IRS).[4][6] Observations by theNEO-/Wide-field Infrared Survey Explorer missions gave a somewhat different result of0.17 and0.38, respectively.[5][8] Determinations of the asteroid's diameter resulted in 11 kilometers for Spitzer and WISE/NEOWISE,[4][5] 15 kilometer for AKARAI and the LCDB's best calculations,[3][6] and 17 kilometers for the preliminary results of the NEOWISE mission.[8]
In October 2008, the discovery of a satellite in orbit ofCevenola was announced. Themoon measures approximately 6 kilometers in diameter.[15][16]
The asteroid was named after theCévennes, a mountain range in southern France at the eastern rim of theMassif Central.[2] Naming citation was first mentioned inThe Names of the Minor Planets byPaul Herget in 1955 (H 121).[2]
