6025 Naotosato, provisional designation 1992 YA3, is an Eoan asteroid from the outer region of the asteroid belt, approximately 19 kilometers in diameter. It was discovered on 30 December 1992, by Japanese astronomer Takeshi Urata at the Nihondaira Observatory in Oohira, Japan.[9] The asteroid was named after Japanese amateur astronomer Naoto Satō.[2]

Orbit and classification

Naotosato is a member of the

606), the largest asteroid family in the outer
main belt, consisting of nearly 10,000 asteroids.

It orbits the Sun at a distance of 2.8–3.2 AU once every 5 years and 3 months (1,919 days). Its orbit has an eccentricity of 0.07 and an inclination of 9° with respect to the ecliptic.[1] The first observation was made at Goethe Link Observatory in 1954, extending the asteroid's observation arc by 38 years prior to its discovery.[9]
