I thought this was going to be a topic about Keppler 22-b. |

Translunar injection: TLI

A couple of things confuse me here: the first is this pretty picture. I have no idea what the multi-colour shapes are, but don't they insinuate that the planet is inwards of the habitable zone? The second one, and I'm not sure if I'm reading this correctly, but the Wikipedia article stated that the temperature was calculated based on a specific albedo. There's more to calculating planetary temperature though- such as the greenhouse effect. And thanks for bringing up Kepler 22-b, Oberron... I though this thread was about that discovery too. But: anyone willing to bet that best case, Kepler 22-b is a precambrian hyperdesert with no hope of ever accomodating complex life?

 As of this year (2012), the same findings seem to still apply. They still think there are oceans on the surface, as well as a greenhouse effect, and I couldn't find any info as to how strong the effect is but since the temperature is still believed to be 24 degrees Celsius, I'm inclined to believe its not that strong. Its considered to have a very stormy weather, especially when it leaves the Habitable Zone for a limited period of time. What bugs me is the tidally locked thing. From my research, tidally locked planets should occur only around red dwarf stars of M2V and lower spectral class. This one is a strange case. Perhaps early in its formation, asteroid or comet impacts have caused the planet to have such a slow rotation around its axis to become nearly tidally locked. But this theory would not explain why it would actually be, tidally locked. Some other potentially habitable worlds:  Kepler 20 f :  Kepler 22 b :

We really ought to be giving some of these exoplanets proper names, or at least the Earthlike ones. |

I was actually thinking of whether or not to start a topic about this. |
