天文学家发现四颗热小行星 环绕着巴纳德之星运行 我们的第二大星座邻居 Astronomers find four hot, small planets orbiting Barnard's Star, our second-closest stellar neighbor.

天文学家发现了四颗围绕巴纳德星运行的小行星，巴纳德星是离地球第二近的恒星系统。 Astronomers have discovered four tiny planets orbiting Barnard's Star, the second-closest star system to Earth. 每颗行星大约占地球质量的20%到30% 短短几天内就绕着恒星运行 使恒星太热 无法支撑生命 Each planet is about 20 to 30% the mass of Earth and orbits the star in just a few days, making them too hot to support life. 调查结果利用MAROON-X仪器得到确认,并在《天体物理学杂志通讯》上发表。 The findings were confirmed using the MAROON-X instrument and are published in The Astrophysical Journal Letters.
