[2][12] Francette is the second largest member of the small Hilda family (001),[4] an asteroid family within the dynamical Hilda group,[3] that stays in an orbital resonance with the gas giant Jupiter.
[1][3] The Wide-field Infrared Survey Explorer (WISE) also characterizes Francette as a dark P-type,[10] while the overall spectral type for members of the Hilda family is typically that of a carbonaceous C-type.
[13]: 23 In July 2016, a rotational lightcurve of Francette was obtained from photometric observations by American astronomers Brian Warner, Robert Stephens and Dan Coley at the Center for Solar System Studies (U80–82) in California.
[8][9][a] According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's WISE telescope, Francette measures between 76.395 and 85.81 kilometers in diameter and its surface has an albedo between 0.037 and 0.046.
[5][6][7][10] The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.0400 and a diameter of 82.13 kilometers based on an absolute magnitude of 9.54.
