1444 Pannonia, provisional designation 1938 AE, is a carbonaceous asteroid from the outer region of the asteroid belt, approximately 29 kilometers in diameter. It was discovered on 6 January 1938, by Hungarian astronomer György Kulin at Konkoly Observatory in Budapest, Hungary.[16] It was named after the ancient province of the Roman Empire, Pannonia.[2]

Orbit and classification[edit]

Pannonia is a C-type asteroid in the outer main-belt. 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.[16]

Photometry[edit]

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).[13] 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).[12]

Diameter and albedo[edit]

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.[4][7][8][9][10][11] 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.[3]

Naming[edit]

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.[2] Naming citation was published on 1 February 1980 (M.P.C. 5182).[17]
