That star is a bit cooler than the sun. "So if the greenhouse warming were similar on this planet, and it had a surface, its surface temperature would be something like 72 Fahrenheit — a very pleasant temperature here on Earth." Kepler 22b is more than twice as large as Earth. One b...

Kepler-22b is 2.4 times as large as Earth and orbits a star very much like our sun. NEXT: The Smallest Exoplanet Kepler-37b: The Smallest Alien Planet NASA/Ames/JPL-Caltech The tiny alien planet Kepler-37b, which was announced in February 2013, is slightly larger than Earth's moon ...
The smallest of the three planets is approximately the size of Mars with a surface temperature of around 400-degrees Celsius (750-degrees Fahrenheit). The planets are thought to be rocky - like Earth - but orbit much closer to their star making them too hot to hold liquid water, making th...
it is scorching hot and unable to maintain an atmosphere or a liquid water ocean. Kepler-22b ...
On Dec. 5 the team announced the discovery of Kepler-22b in the habitable zone of its parent star. It is likely to be too large to have a rocky surface. While Kepler-20e and Kepler-20f are Earth-size, they are too close to their parent star to have liquid water on the surface. "...
22b, the smallest planet found in a habitable zone before the recent discoveries, is very likely a Mini-Neptune, and not a solid planet. In what is denoted the empirical habitable zone, liquid water can exist on the surface of a planet if that planet has sufficient cloud cover. In the ...

Kepler 22b 是地球的两倍大。需要特别注意的一点是它也许不像地球那样含有较多的岩石。它也许像海王星那样是个气态为主的行星。如果这个推测是正确的,那么希望该星球上有生命的迹象是非常渺茫的了。 Kepler 应该在不久的将来还会找到更适合生命存在的强有力的工具。这个卫星现在已经探测到了2300颗可能存在生命的行星-...
