17795 Elysiasegal, provisional designation 1998 FJ61, is an asteroid from the inner regions of the asteroid belt, approximately 5 kilometers in diameter. It was discovered on 20 March 1998, by the Lincoln Near-Earth Asteroid Research team (LINEAR) at the U.S. Lincoln Laboratory Experimental Test Site in Socorro, New Mexico.[5]
The asteroid orbits the Sun at a distance of 2.0–2.8 AU once every 3 years and 8 months (1,352 days). Its orbit has an eccentricity of 0.17 and an inclination of 2° with respect to the ecliptic.[1] The first precovery was taken by the Near-Earth Asteroid Tracking programm in 1996, extending the asteroid's observation arc by 2 years prior to its official discovery observation.[5] Little is known about the asteroids size, composition, albedo and rotation. 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]
It was named for Elysia Segal (b. 1985), 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] Naming citation was published on 14 June 2004 (M.P.C. 52173).[7]
