Glossary term: 人马座
Description: 人马座是黄道带上的一个星座,也就是说,组成这个星座的恒星位于与黄道(由地球绕太阳运行的轨迹所确定的平面)相交的那部分天空。因此,从地球上看,我们会发现太阳和太阳系的其他行星经常落在人马座中。就太阳而言,这发生在每年12月下旬到1月上旬。(当然,那时我们看不到人马座中的恒星。)人马座是国际天文学联合会定义的88个现代星座之一,但其历史可以追溯到更久远的年代——它是公元2世纪的天文学家克罗狄斯·托勒密(Claudius Ptolemy)命名的48个星座之一。值得注意的是,我们银河系的中心就位于人马座,那里有着超大质量黑洞——人马座A*。
