31249 Renéefleming (

rotation period of 3.34 hours.[3] It was named for American soprano Renée Fleming.[1]

Orbit and classification

Renéefleming is a non-

Griqua group, the orbits of the Zhongguos are stable over half a billion years.[4]

It orbits the Sun in the

semi-major axis of 3.25 AU). Its orbit has an eccentricity of 0.27 and an inclination of 2° with respect to the ecliptic.[2] The body's observation arc begins with its first observations at Mount Wilson Observatory in April 1934, almost 64 years prior to its official discovery observation at Caussols.[1]

Physical characteristics

Renéefleming is an assumed C-type asteroid,[3] which agrees with the body's albedo (see below).

Diameter and albedo

According to the survey carried out by the

albedo of 0.053,[6][7] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for a carbonaceous asteroid of 0.057 and calculates a diameter of 6.08 kilometers based on an absolute magnitude of 14.81.[3]
