(11871) Norge is an asteroid of the main inner belt , which was discovered on October 7, 1989 by the Belgian astronomer Eric Walter Elst at the La Silla Observatory of the European Southern Observatory in Chile ( IAU code 809). There had been unconfirmed sightings of the asteroid before: in January 1984 (1984 BL 3 ) at the Palomar Observatory in California and on September 28, 1989 (1989 SJ 8 ) at the La Silla Observatory.
The Italian astronomer Vincenzo Zappalà defined in a publication from 1995 (et al.) That (11871) Norge belonged to the Flora family, a large group of asteroids named after (8) Flora . Asteroids of this family move in a 4: 9 orbital resonance with the planet Mars around the sun . The group is also called the Ariadne family, after the asteroid (43) Ariadne . According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic investigation by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (11871) Norge determined that it could be one of the rare V-asteroids .
(11871) Norge was named on July 5, 2001 after the northern European state of Norway . Norge is the name of Norway in Bokmål , one of the two official standard varieties of Norwegian .
