(3374) Namur is an asteroid of the main outer belt discovered on May 22, 1980 by the Belgian astronomer Henri Debehogne at the La Silla Observatory of the European Southern Observatory in Chile ( IAU code 809).
The asteroid is a member of the Koronis family, a group of asteroids named after (158) Koronis . The timeless (non- osculating ) orbital elements of (3374) Namur are almost identical to those of eleven smaller asteroids, assuming absolute brightness , for example (50898) 2000 GF 47 .
With an eccentricity of 0.0124, the orbit of (3374) Namur around the sun is even more circular than that of the earth's orbit , which is 0.0167.
According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel (3374) assigned Namur to the taxonomic class of the S-asteroids .
(3374) Namur was named on December 12, 1989 after the Walloon city of Namur , where Henri Debehogne studied at the University of Namur .
