3074 Popov, provisional designation Template:Mp, is a carbonaceous Nysian asteroid from the inner regions of the asteroid belt, approximately Script error: No such module "convert". in diameter. It was discovered on 24 December 1979, by Soviet–Russian astronomer Lyudmila Zhuravleva at the Crimean Astrophysical Observatory in Nauchnyj on the Crimean peninsula. The B-type asteroid has an unknown rotation period. It was named after Russian physicist Alexander Stepanovich Popov, an early radio pioneer in Russia.[1][2]
Orbit and classification
Popov is a member of the carbonaceous subgroup of the Nysa family (FIN: 405Script error: No such module "Check for unknown parameters".), a group of asteroids in the inner main-belt not far from the Kirkwood gap at 2.5 AU, a depleted zone where a 3:1 orbital resonance with the orbit of Jupiter exists. The Nysian group is named after its largest member 44 Nysa.[3][4]
It orbits the Sun in the inner asteroid belt at a distance of 2.1–2.6 AU once every 3 years and 7 months (1,307 days; semi-major axis of 2.34 AU). Its orbit has an eccentricity of 0.11 and an inclination of 2° with respect to the ecliptic.[2]
The asteroid was first observed as Template:Mp at the Purple Mountain Observatory in October 1964. The body's observation arc begins with its observations as Template:Mp at Crimea–Nauchnij in December 1975, or four years prior to its official discovery observation.[1]
Physical characteristics
In the SMASS classification, Popov is a B-type asteroid, which have a "brighter" surface than the common carbonaceous C-types.[2]
Diameter and albedo
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Popov measures 9.875 kilometers in diameter and its surface has an albedo of 0.070.[5]
Rotation period
As of 2018, no rotational lightcurve of Popov has been obtained from photometric observations. The body's rotation period, shape and poles remain unknown.[2]
Naming
This minor planet was named after Russian physicist Alexander Stepanovich Popov (1859–1906), who is considered to be the inventor of radio in his homeland and in eastern European countries.[1] The official naming citation was published by the Minor Planet Center on 31 May 1988 (M.P.C. 13174Script error: No such module "Check for unknown parameters".).[6] The lunar crater Popov was also named in his honor.
