It was discovered on July 25, 1950 by the Indiana Asteroid Program at the Goethe Link Observatory in the U.S. state of Indiana.〔 The asteroid orbits the Sun at a distance of 1.8–2.5 AU once every 3.20 years (1,167 days). It has a rotation period of 7.6 hours.〔 Preliminary results from the NEOWISE mission determined a geometric albedo of 0.26,〔 while the ''Light Curve Data Base'' project assumes a lower albedo of 0.20 for the S-type asteroid.〔 The asteroid was named in honor of American physicist Alan Tower Waterman (1892–1967), who was the first director of the U.S. National Science Foundation. He went to Washington to serve with OSRD (1941–45), ONR (1946–51), and NSF (1951–63), after being an academic physicist for 25 years. He was awarded the Karl Taylor Compton Gold Medal for distinguished statesmanship in science, the Public Welfare Medal and the Presidential Medal of Freedom.〔〔 == 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「1822 Waterman」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
