1333 Cevenola, provisional designation 1934 DA, is a stony, binary asteroid from the asteroid belt about 15 kilometers in diameter. It was discovered on 20 February 1934, by French female astronomer Odette Bancilhon at Algiers Observatory, Algeria in Northern Africa.[13] The S-type asteroid is a member of the Eunomia family.[3] More specifically, it is estimated to have a Sq spectral type, which would also agree with its family classification.[12] It orbits the Sun at a distance of 2.3–3.0 AU once every four and a half years (1,561 days). Cevenola's orbit is mildly eccentric (0.13) an tilted by 15 degrees to the ecliptic.[1]
It has an extremely well determined rotation period of 4.88 hours.[6][8][9][10][11] The asteroid has a geometric albedo of 0.21, as measured by the Japanese Infrared Satellite, Akari, and by Spitzer's Infrared Spectrograph (IRS).[4][6] Observations by the NEO-/Wide-field Infrared Survey Explorer missions gave a somewhat different result of 0.17 and 0.38, respectively.[5][7] Determinations of the asteroid's diameter resulted in 11 kilometers for Spitzer and WISE/NEOWISE,[6][7] 15 kilometer for AKARAI and the LCDB's best calculations,[3][4] and 17 kilometers for the preliminary results of the NEOWISE mission.[5]
In October 2008, the discovery a satellite in orbit of Cevenola was announced. The moon measures about 6 kilometers in diameter.[14][15]
The asteroid was named after the Cévennes, a mountain range in southern France at the eastern rim of the Massif Central.[2]
