Re: Earth's cousin?

The star is a red dwarf, so that means it will live for a very long time. The planet may be far enough out that it isn't tidally locked into captured rotation, I hope.

I still would like to know more about 47 Ursae Majoris. The star there is a bit brighter than our Sun, and its slightly larger version of Jupiter is about where our asteroid belt would be in relation to that star. That and the gas giant would serve as a reflector.

Combine a brighter star with a closer gas giant--and that means any Europa type moon might have the effective insolation distance of Mars, and still have a lot of water.
