    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]
