4364 Shkodrov, provisional designation1978 VV5, is a backgroundasteroid from the inner regions of theasteroid belt, approximately 4.5 kilometers in diameter. It was discovered on 7 November 1978, by American astronomersEleanor Helin andSchelte Bus at thePalomar Observatory in California. The asteroid was named after Bulgarian astronomerVladimir Shkodrov.[2]
Shkodrov is a non-family asteroid of the main belt'sbackground population when applying thehierarchical clustering method to itsproper orbital elements.[3][4] Based on osculating Keplerianorbital elements, the asteroid has also been classified as a member of theFlora family (402), a giantasteroid family and the largest family of stony asteroids in the asteroid belt.[5]
It orbits the Sun in theinner main belt at a distance of 2.0–2.7 AU once every 3 years and 7 months (1,297 days;semi-major axis of 2.33 AU). Its orbit has aneccentricity of 0.14 and aninclination of 2° with respect to theecliptic.[1] The body'sobservation arc begins at Palomar Observatory, two nights prior to its official discovery observation.[2]
Shkodrov is an assumed, stonyS-type asteroid, which is also the overallspectral type for members of the Flora family.[5]
In 2010 and 2013, two rotationallightcurves ofShkodrov have been obtained by astronomers at thePalomar Transient Factory in California. Lightcurve analysis of the photometric observations in the R-band gave arotation period of 17.256 and 17.302 hours with a brightness variation of 0.40 and 0.35magnitude, respectively (U=2/2).[5][7] In 2015,Petr Pravec published a refined period of 17.3233 hours and an amplitude of 0.42 magnitude (U=3-).[a]
According to the survey carried out by theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer,Shkodrov measures 4.21 kilometers in diameter and its surface has analbedo of 0.24.[6] TheCollaborative Asteroid Lightcurve Link assumes an identical albedo of 0.24 – derived from8 Flora, the Flora family'sparent body – and calculates a diameter of 4.94 kilometers based on anabsolute magnitude of 13.7.[5]
Thisminor planet was named after Bulgarian astronomerVladimir Shkodrov (1930–2010), professor at theBulgarian Academy of Sciences and founder of theBulgarian National Observatory. The asteroid also honors his collaboration with the discoverers on theInternational Near-Earth Asteroid Survey despite difficult times.[2] The official naming citation was published by theMinor Planet Center on 25 August 1991 (M.P.C. 18645).[9]
