4349 Tibúrcio, provisional designation Template:Mp, is a dark asteroid from the central region of the asteroid belt, approximately 29 kilometers in diameter. It was discovered on 5 June 1989, by German astronomer Werner Landgraf at ESO's La Silla Observatory in northern Chile.[1]
With 53.5°, it had been the asteroid with the smallest angular distance from the Sun ever discovered.[2]Template:Rp It was later named after Brazilian amateur astronomer Júlio Tibúrcio.[3]
Orbit and classification
Tibúrcio orbits the Sun in the central main-belt at a distance of 2.0–3.3 AU once every 4 years and 3 months (1,550 days). Its orbit has an eccentricity of 0.24 and an inclination of 11° with respect to the ecliptic.[4]
One day before its first identification as Template:Mp, a precovery was taken at Lowell Observatory in 1931, extending the body's observation arc by 58 years prior to its official discovery at La Silla.[1]
Physical characteristics
The asteroid has been characterized as an X-type asteroid by Pan-STARRSTemplate:' large-scale photometric survey.[5]
Rotation period
A rotational lightcurve of Tibúrcio was obtained from photometric observations by astronomer David Higgins at the Australian Hunters Hill Observatory (E14Script error: No such module "Check for unknown parameters".) in October 2010. Lightcurve analysis gave a well-defined rotation period of 16.284 hours with a brightness variation of 0.40 magnitude (U=3Script error: No such module "Check for unknown parameters".).Template:Efn
Diameter and albedo
According to the space-based surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its NEOWISE mission, Tibúrcio measures between 24.9 and 30.23 kilometers in diameter, and its surface has a low albedo between 0.034 and 0.061.[4][6][7][8][9][10][11]
Collaborative Asteroid Lightcurve Link assumes an albedo of 0.049 and calculates a diameter of 26.1 kilometers with an absolute magnitude of 11.8.[12]
Naming
This minor planet was named after Brazilian amateur astronomer and student of information science, Júlio César dos Santos Tibúrcio.[3] The official naming citation was published by the Minor Planet Center on 8 June 1990 (M.P.C. 16445Script error: No such module "Check for unknown parameters".).[13]
