Based upon measurement of its trigonometric parallax, it is approximately 390 light years from Earth.〔 The primary component is an A-type main sequence star with a stellar classification of A2 V,〔 an apparent magnitude of +5.50 and an estimated age of 600 million years.〔 The radius of this star is more than three times the radius of the Sun, and the photosphere has an effective temperature of about 10,000.〔 The secondary component has an apparent magnitude of 11.4 and is separated from the primary by an angle of 3.9 arcseconds.〔 An excess emission of infrared radiation suggests the presence of a dusty disk in orbit about the primary. This disk has a mean radius of 105 AU, or 105 times the separation of the Earth from the Sun, and is radiating at a temperature of 85 K.〔 This star system is a probable member of the Ursa Major Moving Group of stars that share a common motion through space.〔 The space velocity components of Epsilon Trianguli are = .〔 ==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「Epsilon Trianguli」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.
