    The asteroid is named after Céluta, a female character in two works of fiction by François-René de Chateaubriand, Atala (1801) and René (1802). The Henry brothers had already named another of their discoveries, 152 Atala, after the heroine of Atala.[3] Both Atala and Céluta are American Indian fictional characters.[4]

    Photometric observations of this asteroid at the Organ Mesa Observatory in Las Cruces, New Mexico during 2010 gave a light curve with a period of 19.842 ± 0.001 hours and a brightness variation of 0.54 ± 0.02 in magnitude.[2]
