2005年，天文学家公布了一颗行星绕双星系统运行的证据。 发现这样的证据在历史上还是第一次。

In 2005, astronomers presented evidence for the first planet orbiting a binarysystem.

但是在双星系中，行星可以如此稳定同时绕双星或单星运行，这究竟现实与否？

But how realistic is it to have a stable planet orbiting one (or both) of the stars in a binary system?

这样一颗行星旋转的平面与我们的不同，并且有可能形成远距双星的轨道。

Such a planet would rotate in a different plane in orientation to our current planet orbits, and probably formed in a wide-binary orbit.
