Carbonaceous background asteroid
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.
