4118 Sveta, or by provisional designation,1982 TH3, is an Eoanasteroid from the outer regions of theasteroid belt, approximately 13 kilometers (8.1 miles) in diameter. It was discovered on 15 October 1982, by Russian astronomerLyudmila Zhuravleva at theCrimean Astrophysical Observatory in Nauchnij, on the Crimean peninsula. The asteroid was named after Soviet cosmonautSvetlana Savitskaya.[1]
Sveta is a member theEos family (606),[3] the largestasteroid family of theouter main belt consisting of nearly 10,000 asteroids.[5] It orbits the Sun at a distance of 2.7–3.3 AU once every 5 years and 3 months (1,916 days;semi-major axis of 3.02 AU). Its orbit has aneccentricity of 0.11 and aninclination of 9° with respect to theecliptic.[2]
The body'sobservation arc begins with its observation as1950 PQ atGoethe Link Observatory in August 1954, more than 28 years prior to its official discovery observation at Nauchnij.[1]
Nospectral type has been determined forSveta. Members of the Eos family are typicallyK-type asteroids.[5]: 23
According to the survey carried out by theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer,Sveta measures 13.232 kilometers in diameter and its surface has analbedo of 0.192.[4]
As of 2018, no rotationallightcurve ofSveta has been obtained fromphotometric observations. The body'srotation period,pole and shape remain unknown.[2]
Thisminor planet was named after Soviet cosmonautSvetlana Savitskaya (born 1948) who, in 1982, became the second woman afterValentina Tereshkova to fly in space, and in 1984 became the first woman to walk in space. Savitskaya has also been a champion of the 1970-FAI World Aerobatic Championships, a competition in sport aviation.[1] The official naming citation was published by theMinor Planet Center on 1 September 1993 (M.P.C. 22500).[6] The asteroid4303 Savitskij was named after her fatherYevgeniy Savitskiy (1910–1990), a Hero of the Soviet Union and himself an aviator and fighter ace during the second World War.[7]
