17795 Elysiasegal, provisional designation 1998 FJ61, is a Nysian asteroid from the inner regions of the asteroid belt, approximately 5 kilometers in diameter. It was discovered on 20 March 1998, by the LINEAR team at Lincoln Laboratory's Experimental Test Site in Socorro, New Mexico, in the United States.[5] The asteroid was named after Elysia Segal, a 2003 ISEF awardee.[2]
Orbit and classification
Elysiasegal orbits the Sun in the inner main-belt at a distance of 2.0–2.8 AU once every 3 years and 8 months (1,351 days). Its orbit has an eccentricity of 0.17 and an inclination of 2° with respect to the ecliptic.[1] A first precovery was taken by the Near-Earth Asteroid Tracking program in 1996, extending the asteroid's observation arc by 2 years prior to its official discovery observation.[5]
Naming
This minor planet was named for Elysia Segal, American actress and first-place winner at the 2003 Intel International Science and Engineering Fair, for her research analyzing the use of proteoglycans as a potential biomarker for congenital hydrocephalus.[2][3][6] The approved naming citation was published by the Minor Planet Center on 14 June 2004 (M.P.C. 52173).[7]
Physical characteristics
Little is known about Elysiasegal's size, composition, albedo and rotation.[1][8] Based on its absolute magnitude of 14.5, its diameter is likely to be between 3 and 7 kilometers, assuming an albedo in the range of 0.05 to 0.25.[4]
