1748 Mauderli, provisional designation 1966 RA, is an eccentric, dark and very reddish Hildian asteroid from the outermost region of the asteroid belt. It was discovered by astronomer Paul Wild at Zimmerwald Observatory near Bern, Switzerland, on 7 September 1966.〔 ''Mauderli'' measures about 50 kilometers in diameter. It is a member of the Hilda family of asteroids which stay in a 3:2 resonance with the gas giant Jupiter. Among the Hilda family, it is one of its members with the highest amplitude of libration relative to the stable periodic orbit.〔 It is also the reddest among the known D-type asteroids.〔 The asteroid orbits the Sun at a distance of 3.0–4.8 AU once every 7 years and 9 months (2,845 days). Its orbit shows an eccentricity of 0.23 and is tilted by 3 degrees to the plane of the ecliptic. It has a rotation period of 6.000 hours.〔〔 Based on observations by the Akari, WISE/NEOWISE spacecraft and missions, it has an albedo of 0.04–0.06.〔〔 The minor planet was named by the discoverer in honor of Sigmund Mauderli (1876–1962), astronomer and director of the Astronomical Institute at the University of Bern from 1921–1946. He devoted much of his time to orbit determination and perturbation computing of minor planets for the Astronomisches Rechen-Institut in Germany.〔 == References == }} 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「1748 Mauderli」の詳細全文を読む スポンサード リンク
