Please answer the following question: Information: - Kitt Peak is a mountain in the U.S. state of Arizona, and at is the highest point in the Quinlan Mountains. It is the location of the Kitt Peak National Observatory. The radio telescope at the Observatory is one of ten dishes comprising the Very Long Baseline Array radio telescope. - 6141 Durda ( 1992 YC3 ) is a Mars - crossing asteroid discovered on December 26 , 1992 by Spacewatch at Kitt Peak . With an absolute magnitude of 14.1 , the asteroid is about 4 -- 9 km in diameter . On 2154 - Sep - 22 the asteroid will pass 0.0088 AU ( 1,320,000 km ; 820,000 mi ) from Mars . - The Kitt Peak National Observatory (KPNO) is a United States astronomical observatory site located on 2,096 m (6,880ft) Kitt Peak of the Quinlan Mountains in the Arizona-Sonoran Desert on the Tohono O'odham Nation, west-southwest of Tucson, Arizona. With 24 optical and two radio telescopes, it is the largest, most diverse gathering of astronomical instruments in the world. The observatory is administered by the National Optical Astronomy Observatory (NOAO). - The Very Long Baseline Array (VLBA) is a system of ten radio telescopes which are operated remotely from their Array Operations Center located in Socorro, New Mexico, as a part of the National Radio Astronomy Observatory (NRAO). These ten radio antennas work together as an array that forms the longest system in the world that uses very long baseline interferometry. The longest baseline available in this interferometer is about . The construction of the VLBA began in February 1986 and it was completed in May 1993. The first astrometrical observation using all ten antennas was carried out on May 29, 1993. The total cost of building the VLBA was about $85 million. What entity does '6141 durda' has the relation 'site of astronomical discovery' with?
A:
kitt peak national observatory
