这颗红色恒星已经耗尽了内核中的氢燃料，正在消耗地壳中仅存的氢，慢慢扩张成一颗红巨星。 扩张成一颗完全红巨星的过程要持续数亿年，最终这颗恒星会吞没任何附近环绕的行星系。

This large red star has exhausted its core hydrogen fuel and is slowly expanding into a red giant, consuming all remaining hydrogen in the stellar shell. While the process of expansion into a full red giant will take hundreds of millions of years, eventually the star will engulf any planetary system orbiting close to it.
