4318 Baťa, provisional designation1980 DE1, is a dark backgroundasteroid from the outermost regions of theasteroid belt, approximately 27 kilometers (17 miles) in diameter. It was discovered on 21 February 1980, by astronomerZdeňka Vávrová at theKleť Observatory in the Czech Republic.[1] TheD-type asteroid has a rotation period of 10.6 hours and is likely elongated in shape.[3] It was named in memory of Czech businessmanTomáš Baťa.[1]
Baťa is a non-family asteroid from the main belt'sbackground population.[4][5] It orbits the Sun in theoutermost asteroid belt at a distance of 2.9–3.6 AU once every 5 years and 9 months (2,113 days;semi-major axis of 3.22 AU). Its orbit has aneccentricity of 0.10 and aninclination of 10° with respect to theecliptic.[2] The body'sobservation arc begins with aprecovery taken atPalomar Observatory in April 1957, almost 23 years prior to its official discovery observation at theKleť Observatory.[1]
Thisminor planet was named in memory ofTomáš Baťa (1876–1932), a world-renowned Czech businessman and founder of theBata Shoe Organization. The officialnaming citation was published by theMinor Planet Center on 8 June 1990 (M.P.C. 16444).[13]
In theSDSS-based taxonomy,Baťa is a very darkD-type asteroid.[11] Thisspectral type is typical in the outermost asteroid belt and often found in the Jupiter trojan population.
In April 2004, a rotationallightcurve ofBaťa was obtained fromphotometric observations by astronomers at thePalomar Transient Factory in California. Lightcurve analysis gave arotation period of10.571±0.2523 hours with a high brightness amplitude of 0.62magnitude, indicative of an elongated, non-spherical shape (U=2).[10]
According to the surveys carried out by the JapaneseAkari satellite and theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer,Baťa measures between 25.79 and 28.26 kilometers in diameter and its surface has analbedo between 0.05 and 0.055.[6][7][8][9] TheCollaborative Asteroid Lightcurve Link assumes a standard albedo for acarbonaceous asteroid of 0.057 and calculates a diameter of 21.09 kilometers based on anabsolute magnitude of 12.11.[3]
