7166 Kennedy, provisional designation 1985 TR, is a stony Nysian
Edward Bowell at Lowell's Anderson Mesa Station near Flagstaff, Arizona, in the United States.[9] The asteroid was named after Malcolm Kennedy of the Astronomical Society of Glasgow.[2]
Orbit and classification
Kennedy is a member of the
hierarchical clustering method to its proper orbital elements.[4]
It orbits the Sun in the inner main-belt at a distance of 2.1–2.8 AU once every 3 years and 9 months (1,384 days). Its orbit has an eccentricity of 0.13 and an inclination of 4° with respect to the ecliptic.[1] The body's observation arc begins with a precovery taken at Palomar Observatory in June 1954, more than 31 years prior to its official discovery observation at Anderson Mesa.[9]
Physical characteristics
Kennedy has been characterized as a common stony
PanSTARRS photometric survey.[8]

Diameter and albedo
According to the survey carried out by the
albedo of 0.267,[5][6] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.21 and calculates a diameter of 4.42 kilometers based on an absolute magnitude of 14.08.[3]
