NASA Has Already Discovered Numerous Potential Exoplanet Candidates

Although there are a few contenders for terraforming in our solar system, that is by no means the only option. After all, the universe is very big. According to some estimations, our galaxy alone has six billion Earth-like planets. That could be more than 19 sextillion in the cosmos. That is 19 with 21 zeros after it; such an absurdly large number that it might as well be a million.

We have only discovered little more than 4,000 of those essentially infinite worlds. They are known as exoplanets, and they can be found anywhere outside of our solar system. Currently, there are about 58 of them on the list of planets that may support life. This indicates that they are around the proper size and distance from the sun. Even if it's feasible that each and every one of them would be a lifeless wasteland, for the time being, they appear to be viable options.
