(15264) Delbrück is an asteroid of the inner main belt , which by the German astronomer Freimut Börngen and Lutz D. Schmadel on 11 October 1990 with the Schmidt telescope of the Karl Schwarzschild Observatory ( IAU code 033) in Tautenburger forest was discovered .
The asteroid belongs to the Nysa group, a group of asteroids named after (44) Nysa (also called the Hertha family, after (135) Hertha ). The timeless (non- osculating ) orbit elements of (15264) Delbrück are almost identical to those of the two smaller ones, if one assumes the absolute brightness of 18.5 and 17.9 compared to 15.1, asteroids 2007 SZ 153 and (437480) 2013 YZ 50 .
According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel (15264) assigned Delbrück to the taxonomic class of the C asteroids .
The asteroid's albedo , at 0.055 (± 0.004), indicates a dark surface. The mean diameter was calculated to be 5.816 (± 0.097) km .
The railway from (15264) Delbrück was secured in 2000 so that numbering could be assigned. The asteroid was named on October 13 of the same year at the suggestion of Freimut Börngen after the biophysicist Max Delbrück (1906–1981) who received the Nobel Prize in Physiology or Medicine in 1969 together with Alfred Day Hershey and Salvador Edward Luria “for their discoveries of the mechanism of reproduction and the genetic structure of viruses ”.
