[3][7]: 13, 23 Jérôme orbits the Sun in the middle main-belt at a distance of 2.3–3.2 AU once every 4 years and 8 months (1,697 days).
[6] Jérôme is a dark C-type asteroid, classified as a hydrated Ch-subtype in the SMASS classification scheme.
[1] According to the surveys carried out by the Infrared Astronomical Satellite IRAS and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Jérôme measures 15.1 and 17.2 kilometers in diameter, and its surface has an albedo of 0.065 and 0.054, respectively.
As of 2017, Jérôme's rotation period, spin axis and shape remains unknown.
[1][8] This minor planet was named by the discoverer in honour of his father, Jérôme Boyer.
