Kepler: Many Red Dwarfs Have Earth-SIzed Planets Too

astroengine writes "Extrapolating from findings by NASA's planet-hunting Kepler Space Telescope, scientists on Wednesday said roughly six percent of so-called red dwarf stars have Earth-sized planets properly positioned around their parent stars so that liquid water could exist on their surfaces. The team looked at 95 candidate planets circling red dwarf stars observed by Kepler and found that at least 60 percent have planets smaller than Neptune. Most were not the right size or temperature to be Earth-like, but three were found to be both warm and approximately Earth-sized. Statistically that would mean six percent of all red dwarf stars should have a Earth-sized planet. Since 75 percent of the closest stars are red dwarfs, the nearest Earth-like world may be just 13 light-years away."

Re:Nice thing about red dwarf stars

One attractive feature of red dwarf stars, it would seem to me, is that they have much longer lifetimes than sun-like stars. More time for complex life to evolve!

On the other hand, being (necessarily, due to temperature issues) much closer to their star, these planets are likely to be tidally locked, which is *not* a good thing for complex life trying to evolve.
