中文百科

象限仪座

象限仪座又称为四分仪座,是以古代用以测量星体位置的一种仪器为名的星座。1795年时天文学家拉朗德将其加入了星座之列,在十九世纪的星图中,象限仪座位于武仙、天龙与牧夫座之间。但是在1920年代,国际天文联合会 (International Astronomical Union, IAU) 在重新制订现行的88个星座时,将象限仪座的大部分区域并入了牧夫座,象限仪座从此成为历史名词。

Quadrans Muralis (Latin for mural quadrant) was a constellation created by the French astronomer Jérôme Lalande in 1795. It depicted a wall-mounted quadrant that he and his nephew Michel Lefrançois de Lalande had charted the celestial sphere with. It was located between the constellations of Boötes and Draco, near the tail of Ursa Major, containing stars between Beta Bootis and Eta Ursae Majoris (Alkaid).
