1030 Vitja, provisional designation1924 RQ, is a darkbackground asteroid from the outer regions of theasteroid belt, approximately 60 kilometers (37 miles) in diameter. It was discovered on 25 May 1924, by Soviet–Russian astronomerVladimir Albitsky at theSimeiz Observatory on the Crimean peninsula.[1] The asteroid was named in honor of Viktor Zaslavskij (1925–1944), a relative of the discoverer.[2]
Vitja is a non-family asteroid from the main belt'sbackground population.[5] It orbits the Sun in theouter asteroid belt at a distance of 2.7–3.5 AU once every 5 years and 6 months (2,014 days;semi-major axis of 3.12 AU). Its orbit has aneccentricity of 0.12 and aninclination of 15° with respect to theecliptic.[3] The asteroid's first recorded observation was made a week after its official discovery atHeidelberg Observatory in June 1924, while itsobservation arc begins more than seven years later atLowell Observatory in October 1931.[1]
Thisminor planet was named by the discoverer after his relative Viktor "Vitja" Viktorovich Zaslavskij (1925–1944), who died duringWorld War II. He was the nephew of Spiridon Zaslavskij, the brother-in-law of the discoverer, after whom the asteroid1330 Spiridonia was later named.[2] No accurate naming citation was given for this asteroid inThe Names of the Minor Planets. The author of theDictionary of Minor Planets,Lutz Schmadel, researched the naming circumstances himself (LDS).[2][15]
Vitja has been characterized as a primitiveP-type and carbonaceousC-type asteroid by theWide-field Infrared Survey Explorer (WISE) andPan-STARRS photometric survey, respectively.[11][14] TheCollaborative Asteroid Lightcurve Link (CALL) assumes it to be a very dark C-type asteroid.[4]
In July 2007, a rotationallightcurve ofVitja was obtained from photometric observations by French amateur astronomerRené Roy. Lightcurve analysis gave arotation period of 5.7014 hours and a brightness variation of 0.18magnitude (U=3-).[12] Another observation by Andrea Ferrero at the Bigmuskie Observatory (B88) in Italy showed a period of 6.332 with an amplitude of 0.21 (U=2).[13]
According to the surveys carried out by the Infrared Astronomical SatelliteIRAS, the JapaneseAkari satellite and theNEOWISE mission of NASA's WISE telescope,Vitja measures between 52.72 and 69.139 kilometers (32.759 and 42.961 mi) in diameter and its surface has analbedo between 0.0280 and 0.05.[6][7][8][9][10][11]
CALL adopts the results obtained by IRAS, that is, an albedo of 0.0326 and a diameter of 64.13 kilometers (39.85 mi) based on anabsolute magnitude of 10.3.[4]
Between 2007 and 2021, 1030 Vitja has been observed tooccult four stars.
