(4093) Bennett is an asteroid of the main belt , which on 4 November 1986 by the astronomer RH McNaught at the Siding Spring Observatory in Australia at a brightness of 17 like was discovered. Subsequently, the asteroid could already be detected on recordings that were also made in 1979 at the Siding Spring Observatory and in 1981, 1985 and 1986 at other observatories, the last of which was only 14 hours before McNaughts observation.
The asteroid is a member of the Eos family, a group of asteroids that were formed by splintering off (221) Eos .
The asteroid was named after the South African amateur astronomer John Caister Bennett (1914–1990). His interest in comets was aroused by what his mother told him about seeing Halley's Comet in 1910. He compiled a catalog of comet-like objects from the southern sky and discovered two comets himself, namely C / 1969 Y1 (Bennett) and C / 1974 V2 (Bennett) . During his search for comets, he was also the first amateur astronomer to discover a supernova, SN 1968L in the galaxy M83 . He was President of the Astronomical Society of Southern Africa (ASSA) and received many honors.
