[8] The C-type asteroid orbits the Sun in the outer main-belt at a distance of 2.3–4.0 AU once every 5 years and 7 months (2,034 days).
[8] In November 2010, a rotational lightcurve for this asteroid was obtained from photometric observations made at the U.S. Shadowbox Observatory in Carmel, Indiana.
[6] Based on NASA's space-based WISE and its subsequent NEOWISE mission, the asteroid has an albedo of 0.11 and 0.12, and a diameter of 19.9 and 20.0 kilometers, respectively,[4][5] while the Collaborative Asteroid Lightcurve Link (CALL) assumes a lower albedo of 0.06, which translates into a larger diameter of 26.6 kilometers, as the lower the albedo (reflectivity), the higher the body's diameter, for a given absolute magnitude (brightness).
[3] This minor planet was named in memory of American astronomer Marc Aaronson (1950–1987), killed in the dome of the 4-meter Nicholas U. Mayall Telescope of the Kitt Peak National Observatory.
His fields of research included the detection the decelerative effect of the Virgo cluster on the Hubble flow, observations of carbon stars in the globular clusters in the Magellanic clouds, and measurement of the large velocity dispersion in dwarf spheroidal galaxies, suggesting that all galaxies do have dark matter halos.
