4318 Baťa, provisional designation Template:Mp, is a dark background asteroid from the outermost regions of the asteroid belt, approximately Script error: No such module "convert". in diameter. It was discovered on 21 February 1980, by astronomer Zdeňka Vávrová at the Kleť Observatory in the Czech Republic.[1] The D-type asteroid has a rotation period of 10.6 hours and is likely elongated in shape.[2] It was named in memory of Czech businessman Tomáš Baťa.[1]
Orbit and classification
Baťa is a non-family asteroid from the main belt's background population.[3][4] It orbits the Sun in the outermost 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 an eccentricity of 0.10 and an inclination of 10° with respect to the ecliptic.[5] The body's observation arc begins with a precovery taken at Palomar Observatory in April 1957, almost 23 years prior to its official discovery observation at the Kleť Observatory.[1]
Naming
This minor planet was named in memory of Tomáš Baťa (1876–1932), a world-renowned Czech businessman and founder of the Bata Shoe Organization. The official Template:MoMP was published by the Minor Planet Center on 8 June 1990 (M.P.C. 16444Script error: No such module "Check for unknown parameters".).[6]
Physical characteristics
In the SDSS-based taxonomy, Baťa is a very dark D-type asteroid.[7] This spectral type is typical in the outermost asteroid belt and often found in the Jupiter trojan population.
Rotation period
In April 2004, a rotational lightcurve of Baťa was obtained from photometric observations by astronomers at the Palomar Transient Factory in California. Lightcurve analysis gave a rotation period of Script error: No such module "val". hours with a high brightness amplitude of 0.62 magnitude, indicative of an elongated, non-spherical shape (U=2Script error: No such module "Check for unknown parameters".).[8]
Diameter and albedo
According to the surveys carried out by the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Baťa measures between 25.79 and 28.26 kilometers in diameter and its surface has an albedo between 0.05 and 0.055.[9][10][11][12] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for a carbonaceous asteroid of 0.057 and calculates a diameter of 21.09 kilometers based on an absolute magnitude of 12.11.[2]
