[2] Hildburg is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements.
All of these asteroids with an unknown meaning have low numbers, beginning with 164 Eva and ending with 1514 Ricouxa, all discovered between 1876 and the 1930s, predominantly by astronomers Auguste Charlois, Johann Palisa, Max Wolf and Karl Reinmuth.
[14] Hildburg is a common stony S-type asteroid according to observations by Richard Binzel conducted at McDonald and Cerro Tololo observatories in May 1984.
[4][12] In March 2014, a rotational lightcurve of Hildburg was obtained from photometric observations by Italian astronomer Andrea Ferrero at the Bigmuskie Observatory (B88) in Mombercelli, Italy.
[11] In April 2008, French amateur astronomer René Roy determined a period of 14.2±1.0 hours with a low amplitude of 0.07±0.02 magnitude (U=2−).
