'''屎星'''位於[[天鴿座]]的一顆恆星,在[[拜耳命名法]]中是'''天鴿座μ星'''('''Mu Columbae''',μ Col),是能以肉眼看見的少數O型星之一{{clarify|reason=how many and says who?|date=December 2016}}。已知這恆星距離[[太陽系]]約1,300[[光年]],但可能有數百年的誤差。在中國的[[二十八宿]]中屬[[參宿]],代表[[星官]][[廁一|廁]]裡的[[糞便]]。 |

這是相對而言自轉較快的一顆恆星,大約每1.5天自轉一周。相較於[[太陽]],直徑是屎星的22%,自轉一周卻要25.4天。但這種自轉速度是此類恆中較典型的。 |

屎星位於天鴿座的一顆恆星,在拜耳命名法中是天鴿座μ星(Mu Columbae,μ Col),是能以肉眼看見的少數O型星之一[需要解释]。已知這恆星距離太陽系約1,300光年,但可能有數百年的誤差。在中國的二十八宿中屬參宿,代表星官廁裡的糞便。
這是相對而言自轉較快的一顆恆星,大約每1.5天自轉一周。相較於太陽,直徑是屎星的22%,自轉一周卻要25.4天。但這種自轉速度是此類恆中較典型的。
基於自行和徑向速度的測量,天文學家知道,這顆星和御夫座AE正以超過200Km/S的速度在相互遠離。它們共同的起源點交會在獵戶四邊形星團中的伐三。最可能的情況是在250萬年前,有兩對聯星的交互作用(碰撞),造成了這些速逃星從徑向上不同的點拋射而逃逸[7]。
語源
在中國天文學,天鴿座μ稱為屎,漢語拼音:Shǐ,意思是”排泄物”或”糞便",因為這顆星是單獨一顆成為一個星官,位置在廁的下方,屬於參宿 [8][9]。
這顆星與大犬座ζ、大犬座λ、天鴿座γ、天鴿座δ、天鴿座θ、天鴿座κ、天鴿座λ 、天鴿座ξ是猿(Al Ḳurūd 、ألقرد - al-qird)[10]。
