3074 Popov, provisional designation1979 YE9, is a carbonaceous Nysianasteroid from the inner regions of theasteroid belt, approximately 10 kilometers (6 miles) in diameter. It was discovered on 24 December 1979, by Soviet–Russian astronomerLyudmila Zhuravleva at theCrimean Astrophysical Observatory in Nauchnyj on the Crimean peninsula. TheB-type asteroid has an unknownrotation period. It was named after Russian physicistAlexander Stepanovich Popov, an earlyradio pioneer in Russia.[1][2]
Popov is a member of the carbonaceous subgroup of theNysa family (FIN:405), a group of asteroids in the inner main-belt not far from theKirkwood 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 member44 Nysa.[5][3]
It orbits the Sun in theinner 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 aneccentricity of 0.11 and aninclination of 2° with respect to theecliptic.[2]
The asteroid was first observed as1964 TZ at thePurple Mountain Observatory in October 1964. The body'sobservation arc begins with its observations as1975 XK1 at Crimea–Nauchnij in December 1975, or four years prior to its official discovery observation.[1]
In theSMASS classification,Popov is aB-type asteroid, which have a "brighter" surface than the common carbonaceousC-types.[2]
According to the survey carried out by theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer,Popov measures 9.875 kilometers in diameter and its surface has analbedo of 0.070.[4]
As of 2018, no rotationallightcurve ofPopov has been obtained fromphotometric observations. The body'srotation period, shape andpoles remain unknown.[2]
Thisminor planet was named after Russian physicistAlexander Stepanovich Popov (1859–1906), who is considered to be theinventor of radio in his homeland and in eastern European countries.[1] The official naming citation was published by theMinor Planet Center on 31 May 1988 (M.P.C. 13174).[6] The lunar craterPopov was also named in his honor.
