The most “Earth-like” planet ever discovered is named Venus. Similar mass, radius, density and just a little bit closer to the sun than Earth. If only Venus had a magnetic field and a moon it would probably be habitable.
I suspect that most if not all of the “Earth-like” exoplanets are actually “Venus-like” or “Mars-like.”
