So Superhabitable planets are planets that are more Earth-like than Earth, their characteristics are: They orbit either a M or K type star (For their long life's) They have a mass about 2 Earths (Because more shallow oceans from stronger gravity means more biodiversity, plus it's the ideal size for plate tectonics) They're near the center of the habitable zone (So they're in the habitable zone longer as their parent star ages) They have a temperature of 25 c (The ideal temperature for plant life as we know it) Looking at all of these, Kepler 442b and GJ 667cf may be candidates for being a Superhabitable planet because they fill in 3 out of 4 requirements, I bet you could figure out the one they haven't met Also, overall, they'll last much longer too, their parent star will last much longer than the Sun, giving the planet a lot of time to have life evolve, and the planet's size means it can protect itself from solar/cosmic radiation much longer than a Earth-sized planet can, which is also a big plus. So what do you guys think about the possibility's of Superhabitable planets?
