恒星占星
你的真实星座 — 以恒星而非季节为基准。
恒星黄道锚定于天空中的真实星座。对约75%的人而言，恒星太阳星座比热带星座退后一个星座。本页是 Synthesis 发布的恒星占星资料中心。
两种黄道
黄道有两种划分方式，两者都描述真实现象。热带黄道将 0° 白羊锚定在春分——太阳北越天赤道的时刻——追踪季节循环，是多数西方占星师所用体系。
真恒星黄道把每个星座锚定在其真实的星座上。由于地轴极其缓慢地摆动（分点岁差），季节零点与恒星已经彼此漂移——相对真实星座边界，如今差距约为 31°。这就是两种黄道之间的差距。
两种框架都描述真实模式。热带占星描述你与季节循环的关系；恒星占星描述你与固定恒星的关系。它们回答关于同一个人的不同问题。
恒星占星与吠陀（Jyotish）占星共享以星空为基准的黄道。Synthesis 采用真正的天文恒星制——国际天文学联合会（IAU）定义的真实星座边界，包括蛇夫座——而非大多数吠陀星盘使用的拉希里岁差，因此你在这里的星座可能与传统吠陀解读不同。

常见问题
什么是恒星占星？
恒星占星将黄道锚定于天空中真实的星座。它计入分点岁差——地轴的缓慢摆动，使季节标记相对背景恒星每 72 年约移动 1°。相对 Synthesis 所采用的真实星座边界，如今回归黄道与真恒星黄道之间的差距约为 31°。
恒星占星与热带占星有何不同？
热带占星将 0° 白羊锚定在春分，使黄道追踪季节循环；恒星占星将 0° 白羊锚定在白羊座恒星位置，使黄道追踪真实星座。对多数人而言，恒星太阳星座比热带星座退后一个星座。
哪种黄道正确——恒星还是热带？
两者均内部一致，测量不同对象。热带描述你与地球季节循环的关系；恒星描述你与天空固定恒星的关系。多数西方占星师使用热带，吠陀占星使用恒星。两者无优劣，回答不同问题。
什么是“真实恒星占星”？
真实恒星采用国际天文学联合会（IAU）定义的真实星座边界，包括第十三星座蛇夫座。它比 Lahiri 恒星更天文精确，但使用范围更小。Lahiri 仍是吠陀占星的标准。
使用恒星制后，我的性格会变吗？
不会——你的性格不变。恒星制与回归制都在描述你星盘中的真实模式。大多数人能在两种解读中都看到自己。恒星制星座往往指向同一原型更扎实或更本质的表达。
如何找到自己的恒星制星座？
想快速查看，可用恒星制太阳星座日期表。要获得完整星盘——太阳、月亮、上升及所有行星位置——请用恒星制出生星盘计算器，输入精确的出生日期、时间和地点。
