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

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.[10]

Physical characteristics

Suruga has been characterized as a bright

PanSTARRS' photometric survey.[8][9]

Rotation and shape

In February 2013, a rotational

U=3), which indicates a nearly spheroidal shape.[5]

These observations supersede a period of 3.4069 hours (Δmag 0.08) of an ambiguous lightcurve, obtained by Japanese astronomers during lightcurve survey of V-type asteroids in December 2002 (

Diameter and albedo

According to the survey carried out by NASA's

albedo of 0.320,[6][7] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 7.13 kilometers with an absolute magnitude of 13.1.[3]

Satellite

During Brian Warner's photometric observations in 2013, it was revealed, that Suruga is a synchronous

semi-major axis of 11 kilometers for the moon's orbit.[4]
