1906 Naef (
prov. designation:1972 RC) is a stony vestoid asteroid from the inner regions of the asteroid belt, approximately 7 kilometers in diameter. It was discovered on 5 September 1972, by Swiss astronomer Paul Wild at Zimmerwald Observatory near Bern, Switzerland.[10] It was later named after Swiss banker and amateur astronomer Robert A. Naef.[2]
Orbit and classification
Naef orbits the Sun in the
Turku Observatory (1943 VF) and McDonald Observatory (1952 DG1) in 1943 and 1952, respectively, remain unused.[10]
Physical characteristics
According to observations by the
albedo of 0.23,[4][5] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.40 and calculates a diameter of 6.6 kilometer with an absolute magnitude of 12.5.[3]
Naef is a
Q-type asteroids.[9]
