2134 Dennispalm (1976 YB) is a main-belt asteroid discovered on December 24, 1976 by Charles T. Kowal at Palomar Observatory.[1][3] 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]
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.[3]
