(8266) Bertelli Main-belt Asteroid
Discovered on 1 October 1986 by Osservatorio San Vittore at Bologna.
Named in memory of Francesco Bertelli (1794-1844), Italian astronomer at the observatory of Bologna and successor to P. Caturegli (1786-1833) as professor of astronomy at the University of Bologna. Only the first volume of his book, Elementi di Meccanica Celeste, was published at Bologna (1841) before his untimely death. He collaborated in the calculation of the Effemeridi, the annual publication initiated in 1715 by E. Manfredi (1674-1739) and that ceased with Bertelli's death in 1844.Naming citation (19990202/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
