HD 66141, also known as HR 3145 and 50 G. Canis Minoris, is the main star of a binary system〔SIMBAD?〕 in the constellation Canis Minor. It is an orange K-type giant, approximately 254 light years from Earth. Its apparent magnitude is +4.39. When first catalogued it was in the Puppis constellation and was designated "13 Puppis", but it subsequently migrated to Canis Minor. Bode gave it the Bayer designation of Lambda Canis Minoris. Over 2003 to 2012 a starspot was periodically dimming its light.〔 ==Planetary system== From December 2003 to January 2012, the team B.-C. Lee, I. Han, and M.-G. Park observed "HD 66141" with "the fiber-fed Bohyunsan Observatory Echelle Spectrograph (BOES) at Bohyunsan Optical Astronomy Observatory (BOAO)".〔 In 2012, a long-period, wide-orbiting planet was deduced by radial velocity. This was published in November. 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「HD 66141」の詳細全文を読む スポンサード リンク
