Kepler-1649c围绕一颗红矮星运行，如果这颗星发生爆发，可能会对其周围的任何生命构成潜在威胁。此外，这颗行星的大气层仍然是个未知数，而且对其尺寸的计算也可能存在偏差。关于这项研究的详细信息已发表在最新一期的《天体物理学杂志快报》上，文章标题为《A Habitable-zone Earth-sized Planet Rescued fro...
Kepler-1649c orbits its small red dwarf star so closely that a year on Kepler-1649c is equivalent to only 19.5 Earth days. The system has another rocky planet of about the same size, but it orbits the star at about half the distance of Kepler-1649c, similar to howVenusorbits our Sun ...
Though inactive, Kepler will continue in its Earth-trailing orbit around the sun, passing through Earth's neighborhood (at a safe distance) in 2060 and again in 2117. Kepler's role as the leading exoplanet-hunting space telescope was taken over by the Transiting Exoplanet Survey Satellite (TE...
