(6673) Degas is an asteroid of the inner main belt that was discovered on March 25, 1971 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery took place during the 1st Trojan survey, during which Tom Gehrels surveyed field plates recorded by the 120 cm Oschin Schmidt telescope of the Palomar observatory at the University of Leiden , eleven years after the start of the Palomar-Leiden- Surveys . The asteroid had already been sighted: on November 5, 1942 under the provisional designation 1942 VL at the Iso-Heikkilä Observatory of the University of Turku and on August 9, 1953 (1953 PG 1 ) at the Crimean Observatory in Simejis .
Mean distance from the sun ( major semi-axis ), eccentricity and inclination of the orbit plane of (6673) Degas lie within the respective limit values that are defined for the Nysa group, a group of asteroids named after (44) Nysa (also called the Hertha family, after (135) Hertha ).
The mean diameter of (6673) Degas was calculated to be about 12.5 km. With an albedo of 0.03, it has a dark surface.
The asteroid was named on April 4, 1996 after the French painter and sculptor Edgar Degas (1834-1917). An impact crater on the northern hemisphere of the planet Mercury was named after Degas as early as 1979 : Mercury crater Degas .
