It was the first entry in John Flamsteed's catalogue of stars in Auriga. When Eugène Joseph Delporte drew up simplified boundaries for the constellations on behalf of the International Astronomical Union in 1930, 1 Aurigae ended up over the border in Perseus. To avoid confusion, the star is now generally known by its Harvard Revised catalogue number, HR 1533. It is an orange K-type giant with an apparent magnitude of +4.88 and lies approximately 520 light years from Earth. ==References== (1 Aurigae ) in SIMBAD 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「1 Aurigae」の詳細全文を読む スポンサード リンク
