4383 Suruga, provisional designation 1989 XP, is a Vestian asteroid and binary system from the inner regions of the asteroid belt, approximately 6.5 kilometers in diameter. It was discovered on 1 December 1989, by Japanese astronomer Yoshiaki Oshima at Gekko Observatory, Japan.[10] The asteroid was named after the former Japanese Suruga Province. Its synchronous minor-planet moon, S/2013 (4383) 1, measures approximately 1.33 kilometers and has a period of 16.386 hours.
Orbit and classification
Suruga is an orbital member of the Vesta family in the inner main-belt.[3] It orbits the Sun at a distance of 2.3–2.6 AU once every 3 years and 9 months (1,380 days). Its orbit has an eccentricity of 0.06 and an inclination of 7° with respect to the ecliptic.[1]
The asteroid was first identified as 1979 BE2 at
