Orbit and characterization
Ariane orbits the Sun at a distance of 2.1â2.4 AU once every 3 years and 4 months (1,219 days). Its orbit has an eccentricity of 0.07 and an inclination of 3° with respect to the ecliptic.[1]
Photometric observations made in 2003 at the U.S. Carbuncle Hill Observatory (912) near Providence, Rhode Island, give a synodic rotation period of 5.529±0.002 hours. The light curve shows a brightness variation of 0.40±0.02 in magnitude.[7]
Naming
This minor planet was named after "Ariane Leprieur", the principal role in the play Le Chemin de Crête by Gabriel Marcel (1889â1973).[2] The official naming citation was first mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 96).[2]
