[1] Desforges is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements.
[10]: 23 Observations with the Wide-field Infrared Survey Explorer (WISE), however, gave a low geometric albedo more typical for an X- or C-type asteroid (see below).
[8] Lightcurve analysis gave a rotation period of 8.804 hours with a high brightness amplitude of 0.69 magnitude, which indicates that the body has a non-spherical shape (U=2).
[4] According to the survey carried out by the NEOWISE mission of NASA's WISE telescope, Desforges measures between 7.692 and 9.390 kilometers in diameter and its surface has an albedo between 0.0635 and 0.080.
[4] This minor planet was named after a French priest Jacques Desforges (1723–1791), who was imprisoned for eight months in 1758 in the Bastille, during which time he planned the construction of a flying machine.
