8077 Hoyle           Discovered 1986 Jan. 12 by E. Bowell at the Anderson Mesa Station of the Lowell Observatory.
Fred Hoyle (b. 1915) is the leading proponent of steady-state cosmology. He predicted an excited state in the carbon atom and contributed extensively to the study of nucleosynthesis in stars. Hoyle served as president of the Royal Astronomical Society from 1971 to 1973. The name was suggested by S. Mitton.
