Kepler-11, also designated as 2MASS J19482762+4154328, [5] is a Sun-like star slightly larger than the Sun in the constellation Cygnus, located some 2,110 light years from Earth. It is located within the field of vision of the Kepler space telescope, the …

开普勒-11（Kepler-11）是一颗类似太阳的恒星；2011年2月2日 NASA 宣布至少有六颗公转周期很短的 太阳系外行星 围绕该颗恒星运转。 该恒星位于 天鹅座，距离地球约2000光年。 这颗恒星是由 开普勒太空望远镜 的小范围巡天发现的。 从地球的方向观察开普勒11的6颗行星会发现所有行星在 凌日 时会从 恒星 盘面通过；且这些行星位置和地球上观测者观测方向的夹角小于1度。 这种状况使科学家们可以经由观测行星凌日现象直接量测行星的公转周期和直径。 电脑模拟显示 …

2024年10月24日 · Kepler-11 b is a terrestrial exoplanet that orbits a G-type star. Its mass is 1.9 Earths, it takes 10.3 days to complete one orbit of its star, and is 0.091 AU from its star. Its discovery was announced in 2010.

Kepler-11b is an exoplanet discovered around the star Kepler-11 by the Kepler space telescope, a NASA-led mission to discover Earth-like planets. Kepler-11b is less than about three times as massive and twice as large as Earth, but it has a lower density (≤ 3 g/cm 3), and is thus most likely not of Earth-like composition. Kepler-11b is the ...

2011年2月1日 · Kepler-11 is a sun-like star around which six planets orbit. At times, two or more planets pass in front of the star at once, as shown in this artist's conception of a simultaneous transit of three planets observed by NASA's Kepler spacecraft on Aug. 26, 2010.

2011年2月2日 · Among the stars with planetary candidates, 170 show evidence of multiple planetary candidates. Kepler-11, located approximately 2,000 light years from Earth, is the most tightly packed planetary system yet discovered. All six of its confirmed planets have orbits smaller than Venus, and five of the six have orbits smaller than Mercury's.
