6141 Durda, provisional designation1992 YC3 is a stony Hungariaasteroid, classified asslow rotator andMars-crosser from the innermost region of theasteroid belt, approximately 3.2 kilometers in diameter. It was discovered on 26 December 1992, bySpacewatch atKitt Peak National Observatory in Arizona, United States.[6]
This Mars-crosser and presumedE-type asteroid is also member of theHungaria family, which form the innermost dense concentration of asteroids in theSolar System. It orbits the Sun in theinner main-belt at a distance of 1.6–2.1 AU once every 2 years and 5 months (895 days). Its orbit has aneccentricity of 0.14 and aninclination of 16° with respect to theecliptic. On 22 September 2154, it will pass 0.0088 AU (1,320,000 km) from Mars.[1]Durda was first identified as1983 AZ2 atKarl Schwarzschild Observatory in 1983, extending the body'sobservation arc by 9 years prior to its official discovery observation at Kitt Peak.[6]
In October 2009, a rotationallightcurve was obtained from photometric observations byBrian Warner at the Palmer Divide Station in Colorado. Lightcurve analysis gave arotation period of460±5 hours with a brightness variation of 0.50magnitude (U=2+).[5]Durda belongs to theTop 100 slow rotators known to exists.
Based on amagnitude-to-diameter conversion,Durda's generic diameter is between 3 and 7 kilometer for anabsolute magnitude of 14.4, and an assumedalbedo in the range of 0.05 to 0.25.[4] Since asteroids in theinner main-belt are typically ofstony rather thancarbonaceous composition, with albedos above 0.20,Durda's diameter can be estimate to measure around 4 kilometers, as the higher its albedo (reflectivity), the lower the body's diameter.[4] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.30 – a compromise value between 0.4 and 0.2, corresponding to the Hungaria asteroids both as family and orbital group – and calculates a diameter of 3.20 kilometers.[3]
Thisminor planet was named in honor of American planetary scientistDaniel D. Durda, who has researched the generation, evolution, size distribution and fragmentation of minor planets, resulting in the formation ofminor-planet moons. He was especially interested in(243) Ida I Dactyl when he was member of theGalileo mission team. Daniel Durda is also a pilot and an artist of astronomical paintings.[2] In 2015, he was awarded theCarl Sagan Medal for "communicating the wonder of planetary science through visual artistry".[7] The approved naming citation was published by theMinor Planet Center on 8 August 1998 (M.P.C. 32345).[8]
