107 Camilla ( /kəˈmɪlə/ kə-mil-ə) is one of the largest main-belt asteroids. It orbits within the Cybele Group, beyond most main-belt asteroids. It has a very dark surface and primitive carbonaceous composition. It was discovered by N. R. Pogson on November 17, 1868, and named after Camilla, Queen of the Volsci in Roman mythology.[1]
Lightcurve analysis indicates that Camilla's pole most likely points towards ecliptic coordinates (β, λ) = (+51°, 72°) with a 10° uncertainty,[2] which gives it an axial tilt of 29°.

On 1 March 2001, a satellite of Camilla was found by A. Storrs, F. Vilas, R. Landis, E. Wells, C. Woods, B. Zellner, and M. Gaffey using the Hubble Space Telescope.[3] It has been designated S/2001 (107) 1 but has not yet received an official name.
Later observations in September 2005 with the VLT allowed the determination of an orbit.[4] Apart from data in infobox, the inclination was found to be 3 ± 1° with respect to an axis pointing towards (β, λ) = (+55°, 75°).[4] Given the ~10° uncertainty in the actual rotational axis of Camilla, one can say that the orbit's inclination is less than 10°.
The satellite is estimated to measure about 11 km in diameter.[5] Assuming a similar density to the primary, this would give it an approximate mass of ~1.5×1015 kg. It has a similar colour to the primary.[3]
