(11278) Telesio Main-belt Asteroid
Discovered on 26 September 1989 by E. W. Elst at La Silla.
Bernardino Telesio (1509-1588) was an Italian philosopher and natural scientist who severely opposed the practice of reasoning without reference to concrete data. His studies of plants and animals led him to believe that heat is the source of life. Francis Bacon called him “the first of the moderns”.Naming citation (20000320/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
