1444 Pannonia ( prov. designation: 1938 AE) is a carbonaceous background asteroid from the outer region of the asteroid belt, approximately 29 kilometers (18 miles) in diameter. It was discovered on 6 January 1938, by Hungarian astronomer György Kulin at Konkoly Observatory in Budapest, Hungary. [17] It was named after the ancient province of the Roman Empire, Pannonia. [3]

Orbit and classification

Pannonia is a non- family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements. It orbits the Sun at a distance of 2.7–3.6  AU once every 5 years and 7 months (2,044 days). Its orbit has an eccentricity of 0.14 and an inclination of 18 ° with respect to the ecliptic. [1] Pannonia's observation arc begins 3 weeks after its official discovery at Konkoly, as no precoveries were taken, and no prior identifications were made. [17]

Naming

This minor planet was named for Pannonia, an ancient province of the Roman Empire, which was partially located over the territory of the present-day western Hungary. [3] The official naming citation was published by the Minor Planet Center on 1 February 1980 ( M.P.C. 5183). [18]

Physical characteristics

Rotation period

In April 2001, astronomer Colin Bembrick obtained the first rotational lightcurve of Pannonia at Tarana Observatory ( 431) in Australia. Lightcurve analysis gave a well-defined rotation period of 10.756 hours with a brightness amplitude of 0.16 magnitude ( U=3). [14] In 2002 and 2004, photometric observations by French astronomers Laurent Bernasconi and Bernard Christophe Additional periods of 6.2 and 6.205 hours with an amplitude of 0.57 and 0.37, respectively ( U=2-/2). [13]

Diameter and albedo

According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Pannonia measures between 26.36 and 31.49 kilometers in diameter, and its surface has an albedo between 0.04 and 0.47. [5] [8] [9] [10] [11] [12] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0501 and a diameter of 27.14 kilometers with an absolute magnitude of 11.7. [4]
