Kepler 442b is an Earth-sized exoplanet orbiting within the habitable zone of the K-type main sequence star, Kepler-442, around 1,206 light years from Earth in the Lyra constellation. In 2009, NASA's Kepler spacecraft was observing stars on its photomete
今天这个Kepler-452b就是随着2013年5月之前的一批新成果一起发布的。我感觉有点开普勒望远镜在系外行星领...
这颗行星围绕的恒星Kepler452（注意没有b）比太阳大一点，老一点（年龄60亿年），这颗行星直径比地球大...
The new planets found by Kepler compared to the Earth (Image: NASA) The two Earthlike planets are Kepler-438b, which is 475 light years away, 12 percent larger than the Earth, and circles its star in 35.2 days; and Kepler-442b, which is 1,100 light years away, 33 percent bigger, ...
“开普勒-438b”是一颗体积与地球相近的岩石质系外行星，位于红矮星开普勒-438的宜居带，在天球上位于天琴座。该行星是由开普勒空间望远镜以观测行星通过母恒星盘面前，使恒星光度微幅下降的凌日法发现。美国国家航空航天局（NASA）于2015年1月6日宣布确认发现该行星。该行星直径比地球长12%，距离地球470光年，公转时间...
Two of the newly validated planets, Kepler-438b and Kepler-442b, are less than 1.5 times the diameter of Earth. Kepler-438b, 475 light-years away, is 12 percent bigger than Earth and orbits its star once every 35.2 days. Kepler-442b, 1,100 light-years away, is 33 percent bigger th...
The two Earthlike planets are Kepler-438b, which is 475 light years away, 12 percent larger than the Earth, and circles its star in 35.2 days; and Kepler-442b, which is 1,100 light years away, 33 percent bigger, and has a "year" of 112 days. Though their shorter years indicate the...
Kepler-438b orbits at a distance of\n0.166AU to its host star, and hence may be susceptible to atmospheric\nstripping. Our sample is taken from the Habitable Exoplanet Catalogue, and\nconsists of the stars Kepler-22, Kepler-61, Kepler-62, Kepler-174, Kepler-186,\nKepler-283, Kepler-...
Due to the youth of the Kepler-78 system and the small planetary orbital separation, the planet may still retain a collisional secondary atmosphere capable of conducting heat from the day to the nightside. Instead, the presence of an outgassing magma ocean on the dayside and the low high-...
