2349 Kurchenko, provisional designation 1970 OG, is a background

rotation period of 8.6 hours and possibly a spherical shape.[4]

Orbit and classification

Kurchenko is a non-

semi-major axis of 2.77 AU). Its orbit has an eccentricity of 0.12 and an inclination of 17° with respect to the ecliptic.[3] The body's observation arc begins with its observation as 1957 WM1 at Goethe Link Observatory in November 1957, almost 13 years prior to its official discovery observation at Nauchnij.[1]

Occultation

On 19 October 2008, the asteroid

occulted the star TYC 0160-01337-1. All five observers reported a negative result.[12]

Physical characteristics

In the

SMASS classification, Kurchenko is an Xc-subtype that transitions between the X-type and the carbonaceous C-type asteroids.[3] It is also an assumed C-type.[4]

Rotation period

In April 2010, a rotational

U=2).[10]

Diameter and albedo

According to the surveys carried out by the Japanese

albedo between 0.071 and 0.206.[6][7][8][9]

The Collaborative Asteroid Lightcurve Link assumes a standard albedo for a carbonaceous asteroid of 0.057 and calculates a diameter of 27.34 kilometers based on an absolute magnitude of 11.54.[4]
