研究人员证实,Glisee 229B最初被认为是一个单一的棕色侏儒,实际上是由两个棕色侏儒相互绕行的二进制系统。 Researchers have confirmed that Gliese 229B, initially thought to be a single brown dwarf, is actually a binary system of two brown dwarfs orbiting each other. 根据智利超大型望远镜的观测结果,这一发现解决了以前关于该望远镜相对于其质量的微弱问题。 This revelation, based on observations from the Very Large Telescope in Chile, resolves previous questions about its dimness relative to its mass. 这对双胞胎距离大约 18 光年，每 12 天绕对方运行一次，这表明宇宙中可能存在更多隐藏的褐矮星对。 The twins, about 18 light-years away, orbit each other every 12 days, suggesting the possibility of more hidden brown dwarf pairs in the universe.
