jude_rookYou can find basic info on this K star here. Its luminosity is only 5 percent that of Sol, giving it a life zone from 0.15 to 0.33 AU, with an Earth twin distance of 0.22. The Earth twin would have a 37-day year. Keep in mind, though, that Groombridge 1618 is likely not old enough to have a truly Earthlike world, unless we terraform one.
