It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory in the middle of World War II on 14 January 1942.〔 The asteroid orbits the Sun at a distance of 3.0–3.1 AU once every 5 years and 4 months (1,948 days). Its nearly circular orbit is inclined by 11 degrees to the ecliptic. It has a relatively long rotation period of 19 hours〔 and an assumed geometric albedo of 0.06 for a C-type asteroid.〔 It was named in honor of Slovak astronomer Ľubor Kresák (1927–1994) from the Slovak Academy of Sciences in Bratislava and president of IAU's Commission 20 in the 1970s. He is well-known for his theoretical work on meteors and the question of their relationship with comets and minor planets, as well as for the rediscovery of the short-period comet 41P/Tuttle–Giacobini–Kresák at the Skalnaté Pleso Observatory in 1951.〔 == 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「1849 Kresák」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.
