(6309) Elsschot is an asteroid of the outer main belt , which was discovered on March 2, 1990 by the Belgian astronomer Eric Walter Elst at the La Silla Observatory ( IAU code 809) of the European Southern Observatory in Chile .
It was named after the Flemish writer Willem Elsschot (1882-1960), a pseudonym for Alphonsus Josephus de Ridder , one of the few classics of Dutch-language literature, which enjoys great and lasting popularity both with literature connoisseurs and the general public.
The celestial body belongs to the Eos family, a group of asteroids, which typically have large semi-axes from 2.95 to 3.1 AU , bounded inward by the Kirkwood gap of the 7: 3 resonance with Jupiter , and orbital inclinations between 8 ° and 12 °. The group is named after the asteroid (221) Eos . The family is believed to have emerged from a collision more than a billion years ago.
