17795 Elysiasegal, provisional designation 1998 FJ61, is an asteroid from the inner regions of the asteroid belt, roughly 5 kilometers in diameter. It was discovered on 20 March 1998, by the Lincoln Near-Earth Asteroid Research (LINEAR) at Magdalena Ridge Observatory, in Socorro, New Mexico.[4]
The asteroid orbits the Sun at a distance of 2.0–2.8 AU once every 3 years and 8 months (1,351 days). Its orbit shows an eccentricity of 0.17 and is tilted by 2 degrees to the plane of the ecliptic. Little is known about the asteroids size, composition, albedo and rotation, despite having a well-observed orbit with the lowest possible uncertainty – a condition code of 0 – and an observation arc that spans over a period of two decades.[1] Based on its absolute magnitude of 14.5, its diameter could be anywhere between 3 and 7 kilometers, assuming an albedo in the range of 0.05 to 0.25.[3]
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][5]
