[2] Kirkwood belongs to the orbital Hilda group, which is located outermost part of the main belt.

[4] Asteroids in this dynamical group have semi-major axis between 3.7 and 4.2 AU and stay in a 3:2 resonance with the gas giant Jupiter.

[10] In October 2012, a rotational lightcurve of Kirkwood was obtained from photometric observations at the Etscorn Campus Observatory (719) in New Mexico, United States.

[6][7][8] The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.0517 and a diameter of 51.88 kilometers based on an absolute magnitude of 10.26.

[4] This minor planet was named in memory of American astronomer Daniel Kirkwood (1814–1895), long-time professor of mathematics at Indiana University.
