系外行星巴纳德 b 的质量只有金星的一半，在 3.2 个地球日内围绕离太阳最近的单颗恒星巴纳德星运行。 Exoplanet Barnard b, half the mass of Venus, orbits the closest single star to our Sun, Barnard's Star, in 3.2 Earth days.

天文学家发现了一个外行星 叫做巴纳德 b 环绕巴纳德之星的外行星, 巴纳德之星是离太阳最近的一颗恒星, 距离我们的太阳只有六光年之遥。 Astronomers have discovered an exoplanet named Barnard b orbiting Barnard's Star, the closest single star to our Sun, located six light-years away. 巴纳德b 拥有约一半的金星质量 并在短短三天的地球日内完成一个轨道 Barnard b has about half the mass of Venus and completes an orbit in just over three Earth days. 研究人员认为附近可能还有3名外行星候选人 Researchers suggest there may be three more exoplanet candidates nearby. 尽管离恒星很近 巴纳德b太热了 喝不到液态水 Despite its proximity to the star, Barnard b is too hot for liquid water. 研究结果在天文学和天体物理学中发表。 The findings were published in Astronomy and Astrophysics.
