內容簡介
“房宿四”是天文學專有名詞。來自中國天文學名詞審定委員會審定發布的天文學專有名詞中文譯名，詞條譯名和中英文解釋數據著作權由天文學名詞委所有。
用小型望遠鏡觀看，可以發現房宿四是一個由相距14弧秒、實際距離至少2200天文單位的兩顆成員星組成的雙星系統。二者均為灼熱的光譜型為B型的恆星，質量至少為太陽的10倍，其壽命會太陽短。預計二者都會以超新星爆炸的形式結束它們的進化歷程。
房宿四1，二者更亮的一顆，在0.5弧秒（約80天文單位）遠處有另外一個伴星。房宿四1和房宿四2都被認為是分光雙星，這樣的話，整個恆星系統的恆星數量就達到5顆。
由於接近黃道，房宿四可以被月球和行星（很少）掩食。房宿四最近一次被行星掩食是在1971年5月13日被木星掩食。[1]
中國天文
公元四五千年前，中國就開始天文觀測，以後積累了大量文獻資料。古人總把世界的一切看作是一個整體，認為星空的變化，關係著地上人們的吉凶禍福，認為人事變遷、災害和天氣，都可從天象得到預兆。所以，不管研究歷史、災害、氣候變化等等，一涉及古代文獻，都會碰到天象記錄。現在的科學，不僅掌握了古時觀察得到的五大行星的運動規律，還掌握了全部九大行星、成千小行星以及許多慧星的運動軌道，可以推算出任何時刻的星空圖象。甚至不懂天文的人，使用星空軟體，也能很快地求得，公元前後4000年之內任一時刻的天象，以驗證歷史記錄。行星的位置總離不開黃道附近，外國用黃道十二宮記錄，我國則用二十八宿。但是，不僅上述軟體沒有標註二十八宿，就是圖書資料里，也難查到各星宿的組成、圖象和具體位置。
雖然如此，但已能滿足一般需要了。故公布於下。圖中諸星旁的數字，就是星名“某宿幾”。S形黃線是黃道。雖說二十八宿是標記月亮的，但有些星宿偏離黃道，且二十八宿並不等寬。為了區分清楚，相鄰星宿是用兩種不同的顏色繪的。作為比照，用黃色畫上西方的十二宮。除牡羊座外，十二宮都壓著黃道，各星座名則依次注在圖上方。另外又加了7個與二十八宿有關的星座，它們都不在黃道上，其星座名則依次注在圖下方。
