2939 Coconino, provisional designation 1982 DP, is a stony Nysian
Edward Bowell at Lowell's Anderson Mesa Station in Flagstaff, United States.[8] It is named after the Coconino County in Arizona.[2]
Orbit and classification
Coconino is a stony S-type asteroid and a member of the main-belt's Nysa family, which is named after its largest member 44 Nysa. It orbits the Sun in the inner main-belt at a distance of 2.0–2.8 AU once every 3 years and 10 months (1,392 days). Its orbit has an eccentricity of 0.16 and an inclination of 4° with respect to the ecliptic.[1] It was first identified as 1952 HU3 at McDonald Observatory in 1952, extending the body's observation arc by 30 years prior to its official discovery observation at Flagstaff.[8]

Diameter and albedo
According to the survey carried out by NASA's
albedo of 0.512,[4][5] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and consequently calculates a larger diameter of 9.40 kilometers, using an absolute magnitude of 12.5.[3]
