3322 Lidiya, provisional designation1975 XY1, is a stony Phocaeaasteroid and potentiallyslow rotator from the inner regions of theasteroid belt, approximately 7 kilometers in diameter. It was discovered on 1 December 1975, by Soviet astronomerTamara Smirnova at theCrimean Astrophysical Observatory in Nauchnij, on the Crimean peninsula.[9] The asteroid was named after Russian aviatorLidiya Zvereva.[2]
Lidiya is a member of thePhocaea family (701),[4] a largeasteroid family ofinner-belt asteroids with a stony composition.[10]: 23 It orbits the Sun at a distance of 1.9–2.9 AU once every 3 years and 8 months (1,351 days). Its orbit has aneccentricity of 0.22 and aninclination of 23° with respect to theecliptic.[1]
The body'sobservation arc begins with its first identification as1975 VJ6 at Nauchnij in November 1975, one month prior to its official discovery observation.[9]
Lidiya has been characterized as a stonyS-type asteroid byPanSTARRS photometric survey.[8]
In December 2012, a fragmentary rotationallightcurve of Lidiya was obtained from photometric observations at the Altimira Observatory (G76) in California. Lightcurve analysis gave arotation period of 710 hours with a brightness amplitude of 0.60magnitude (U=1).[7] This would make Lidiya one of theslowest rotators known to exist. However, since the lightcurve has such a poor quality rating, it is only apotentially slow rotator.
According to the survey carried out by theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer, Lidiya measures 6.388 and 7.189 kilometers in diameter and its surface has analbedo of 0.350 and 0.3776, respectively.[5][6]
TheCollaborative Asteroid Lightcurve Link assumes an albedo of 0.23 – derived from25 Phocaea, the Phocaea family's largest member and namesake – and calculates a diameter of 7.99 kilometers based on anabsolute magnitude of 12.7.[3]
Thisminor planet was named after Russian aviator Lidiya Vissarionovna Zvereva (1890–1916), the first Russian female pilot, who began flying in 1911. She was also an instructor of other pilots and involved in the construction of airplanes.[2] The official naming citation was published by theMinor Planet Center on 4 October 1990 (M.P.C. 17027).[11] The crater on Venus,Zvereva was also named in her honor in 1985.[a]
