3669 Vertinskij, provisional designation1982 UO7, is a stony Florianasteroid from the inner regions of theasteroid belt, approximately 6.5 kilometers (4 miles) in diameter. It was discovered on 21 October 1982, by Soviet astronomerLyudmila Karachkina at theCrimean Astrophysical Observatory in Nauchnij, on the Crimean peninsula.[1] TheS-type asteroid was named for Russian artistAlexander Vertinsky.[1]
Vertinskij is a member of theFlora family (402),[4][3] a giantasteroid family and the largest family of stony asteroids in the main-belt.[9] It orbits the Sun in theinner asteroid belt at a distance of 2.1–2.4 AU once every 3 years and 3 months (1,203 days;semi-major axis of 2.21 AU). Its orbit has aneccentricity of 0.07 and aninclination of 5° with respect to theecliptic.[2]
The body'sobservation arc begins with aprecovery taken at thePalomar Observatory in November 1949, nearly 33 years prior to its official discovery observation at Nauchnij.[1]
In theSMASS classification,Vertinskij is a common stonyS-type asteroid.[2]
In December 2015,photometric observations ofVertinskij at theOakley Southern Sky Observatory gave no conclusive results due to excessive noise and/or insufficient data.[7] As of 2018, the body'srotation period,pole and shape remain unknown.[4]
According to the survey carried out by theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer,Vertinskij measures between 6.243 and 6.467 kilometers in diameter and its surface has analbedo between 0.2229 and 0.238,[5][6] while theCollaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from8 Flora, theparent body of the Flora family – and calculates a diameter of 6.51 kilometers based on anabsolute magnitude of 13.1.[4]
Thisminor planet was named after Russian artist and poetAlexander Vertinsky (1889–1957). The official naming citation was published by theMinor Planet Center on 12 September 1992 (M.P.C. 20836).[10]
