(3825) Nuremberg is an asteroid of the inner main asteroid belt , which was discovered on October 30, 1967 by Luboš Kohoutek at the Hamburg observatory in Bergedorf .
The asteroid is estimated to be 16.6 kilometers in diameter. The estimation of the diameter is based on the knowledge of the distance and apparent brightness, as well as an estimated reflectivity of the light, the so-called albedo . For example, an elliptical shape with dimensions of 13 km × 20 km is conceivable. It takes 3.36 years for the sun to orbit. It is believed to have emerged as a fragment from a collision between two larger planets about 500 million years ago.
discovery
There is evidence that Nuremberg was first observed by the Hamburg-Bergedorf observatory on the night of April 12th to 13th, 1915. It was not possible to determine the path that would have enabled it to be found again. Further observations were made in 1935 and 1952, but no connection between the observations was recognized. The asteroid received several preliminary names during these years (A915 GA = 1935 ED = 1952 HJ). On October 30, 1967, Luboš Kohoutek observed the asteroid over a period of two weeks. This enabled an orbit to be determined, and the asteroid was given the preliminary designation 1967 UR. Further observations from 1967 to 1983 could later be assigned to the same object (1973 SE5 = 1975 BQ1 = 1980 TN11 = 1983 RD4).
designation
Further observations were made after 1967, whereupon Nuremberg received the serial number 3825 on May 31, 1988 by the International Astronomical Union . At that time, his path was considered secure. The observations in the years before and after 1967 could be linked. Luboš Kohoutek was granted the right to name it, but he did not make use of it.
This asteroid has been called »Nuremberg« since October 15, 2004. The IAU decided to give it a name on the occasion of the ceremonial commissioning of the new large main telescope at the Regiomontanus observatory .
