(10090) Sikorsky is an asteroid of the main inner belt , which was discovered by the Soviet astronomers Lyudmyla Karachkina and Galina Kastel on October 13, 1990 at the Crimean Observatory in Nautschnyj ( IAU code 095). There had been several sightings of the asteroid before: on December 9, 1950 under the provisional designation 1950 XD 1 at the Palomar Observatory in California , on September 20, 1979 (1979 SJ 12 ) at the Swedish observatory Kvistaberg and on February 8, 1988 ( 1988 CD) at the Japanese Geisei Observatory .
The asteroid belongs to the Vesta family , a large group of asteroids named after (4) Vesta , the second largest asteroid and third largest celestial body in the main belt. The timeless (non- osculating ) orbital elements of (10090) Sikorsky are almost identical to those of five smaller ones (if one considers the absolute brightness of 15.5, 16.3, 16.8, 17.3 and 17.6 compared to 13, 4) Asteroids: (38876) 2000 SX 120 , (65816) 1996 TW 28 , (255594) 2006 OE 14 , (408629) 2014 KM 99 and (459602) 2013 HD 25 .
(10090) Sikorsky was named on May 23, 2000 after the aviation pioneer Igor Sikorski (1889–1972). A lunar crater on the eastern back of the moon was named after Sikorski as early as 1979 : Sikorsky lunar crater .
