( 3825 ) Nürnberg is an asteroid of the inner main asteroid belt, the 30 October 1967 by Luboš Kohoutek at the observatory in Hamburg- Bergedorf. was detected.
The diameter of the asteroid is estimated to be 16.6 km. The estimation of the diameter is based on the knowledge of the distance and the apparent brightness, as well as an estimated reflectance of the light, the so-called albedo. For example, an elliptical shape having dimensions of 13 km x 20 km are conceivable. It requires 3.36 years for an orbit around the sun. Presumably he was going about 500 million years ago produced a fragment from a collision between two larger planets.
Discovery
Nuremberg was proven for the first time observed in the night of 12 to 13 April 1915 by the Observatory Hamburg- Bergedorf. A determination of the web, which would have allowed a retrieval could not be performed. Further observations were made in 1935 and 1952, an association of observations, however, was not recognized. The asteroid was in these years several provisional names ( A915 GA ED = 1935 = 1952 HJ). On October 30, 1967 Luboš Kohoutek observed the asteroid over a period of two weeks. This allowed a determination of the orbit and the asteroid was given the provisional designation 1967 UR. Further observations from 1967 to 1983 could be assigned to the same object later (1973 SE5 = 1975 = 1980 BQ1 TN11 = 1983 RD4 ).
Designation
After 1967, further observations were made, what Nuremberg was the serial number 3825 by the International Astronomical Union on 31 May 1988. Its orbit was at this time as certain. The observations in the years before and after 1967 could be related. Luboš Kohoutek was awarded the right to the name, which, however, he did not use.
The name " Nuremberg " takes this asteroid since October 15, 2004. Decision of the IAU for the naming took place at the ceremonial opening of the new large main telescope of Regiomontanus Observatory.
