The most “Earth like” planet ever found is almost the exact same size and mass as Earth and orbits a yellow dwarf star at relatively close to the same orbit as Earth. It is called Venus and I would not want to live there.
I suspect that most or all “Earth like” exoplanets are at best Venus like.
If Mars was closer to the size of Earth, so that it had a denser atmosphere, it too would still not be easily habitable.
Well, send Brian Stelter, Stacy Abrams and several other blimps to investigate, and boldly go where no man has gone before.
