(25,857 posts)Pretty much every single star we look at has planets. However, most of them are not in the Goldilocks zone, where life might be possible. Plus, some 70% of stars in our galaxy are red dwarfs. Very, very, very different from our sun. If a planet around a red dwarf is conducive to life, what might that life be like? Hmmmm?
Here's something else to think about. Our planet has a very large moon, which clearly has been important to life on this planet. It gave us tides, also important. Some other small planet around a red dwarf star, even in that star's Goldilocks zone, even if it has a moon, even if lots of other things are in line to start life, do you understand how very long it took life to get established on this planet?
Plus, our planetary system seems quite different from any other planetary system we've found so far. Our inner rocky planets, our outer gas giants. A lot of other planetary systems have been found, but none are remotely like ours. Hmmmm.
