    2134 Dennispalm, provisional designation 1976 YB is a main-belt asteroid discovered on December 24, 1976, by Charles T. Kowal at Palomar Observatory.[6][7]

    Photometric observations made in 2003 at the Carbuncle Hill Observatory near Providence, Rhode Island, give a synodic rotation period of 4.114 ± 0.002 hours. The light curve shows a brightness variation of 0.37 ± 0.05 in magnitude.[7]

    It is named in honor of C. Dennis Palm (1945–1974), who worked as a night assistant at Caltech's 48" Schmidt telescope on Palomar Mountain in the 1960s and later at Caltech's 60" reflecting telescope, also on Palomar.[2] The approved naming citation was published by the Minor Planet Center before November 1977 (M.P.C. 4788).[8]
