NASA has found what could be called Earth2. Colonization is possible if we can develop FTLs in the near future.
TOI 700 d orbits a star about 40 per cent the size of the sun and half its temperature. It’s fairly close to the star, orbiting in what is called the habitable zone – the area around a star that is just warm enough for water on a world’s surface to remain liquid but not so hot that it evaporates. This exoplanet gets 86 per cent as much sunlight as Earth.
