1952 Hesburgh, provisional designation Template:Mp, is a rare-type carbonaceous asteroid from the outer regions of the asteroid belt, approximately 37 kilometers in diameter.
It was discovered on 3 May 1951, by IU's Indiana Asteroid Program at Goethe Link Observatory near Brooklyn, Indiana, United States.[1] It was named for Father Theodore M. Hesburgh.[2]
Orbit and classification
Hesburgh orbits the Sun in the outer main-belt at a distance of 2.7–3.6 AU once every 5 years and 6 months (2,005 days). Its orbit has an eccentricity of 0.14 and an inclination of 14° with respect to the ecliptic.[3] It was first identified as Template:Mp at Johannesburg Observatory in 1936. The body's observation arc begins at Goethe, five days after its official discovery observation.[1]
Physical characteristics
Lightcurve
In March 2005, a rotational lightcurve of Hesburgh was obtained from photometric observations by American astronomer Brian Warner at his Palmer Divide Observatory in Colorado. Lightcurve analysis gave a longer-than average rotation period of 47.7 hours with a brightness variation of at least 0.18 magnitude (U=2Script error: No such module "Check for unknown parameters".).[4]Template:Efn
Spectral type
In the Tholen taxonomy, Hesburgh is a rare CD: spectral type,[3] an intermediary between the common carbonaceous C-type asteroid and the dark D-type asteroid, which is typical among the Jupiter trojans beyond the main-belt. Another asteroid with a CD:-type is 691 Lehigh.
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, Hesburgh measures between 32.39 and 41.27 kilometers in diameter and its surface has an albedo between 0.078 and 0.1041.[5][6][7][8][9] The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.1041 and a diameter of 35.55 kilometers with an absolute magnitude of 10.32.[10]
Naming
This minor planet was named after American Theodore M. Hesburgh (1917–2015), a priest and president of the University of Notre Dame in Notre Dame, Indiana. He was also a member of the National Science Board and played a decisive role for the founding of the Kitt Peak National Observatory, as well as of the Chilean Cerro Tololo Interamerican Observatory during the 1960s.[2] The approved naming citation was published by the Minor Planet Center on 1 January 1981 (M.P.C. 5688Script error: No such module "Check for unknown parameters".).[11]
