银河系中速度最快的恒星将用于验证相对论

天文学家发现了一颗环绕银河系超大质量黑洞运行的S型星，其运行速度与近心点距离均创下新纪录。这颗恒星将为科学家提供验证相对论，特别是伦泽-蒂林效应的绝佳机会。

Astronomers have discovered another S star, the population of stars that orbits the Milky Way's SMBH. This one is the fastest of them all, and also comes closest to the SMBH. It will let astronomers test relativity, especially the Lense-Thirring effect.
