4383 Suruga
asteroid
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 and it was discovered on 1 December 1989, by Japanese astronomer Yoshiaki Oshima at Gekko Observatory, Japan. The asteroid was named after the former Japanese Suruga Province. Its synchronous minor-planet moon 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. 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.
The asteroid was first identified as 1979 BE2 at Crimea–Nauchnij in 1979. Its observation arc begins in 1981, when it was identified as 1981 UD10 at the Australian Siding Spring Observatory, extending the body's observation arc by 8 years prior to its official discovery observation.
Physical characteristics
Suruga has been characterized as a bright V-type asteroid by PanSTARRS' photometric survey.
Rotation and shape
In February 2013, a rotational lightcurve of Suruga was obtained from photometric observations by American astronomer Brian Warner at his Palmer Divide Observatory (714) in Colorado.

Why this record matters
A short description can identify a subject without explaining its stakes. For “4383 Suruga”, the useful work is to connect “asteroid” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 6, 2026. The linked authority identifier is Q153870. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1989, 1979, 1981 and 2013.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
