What planet can replace Earth?
Could you please elaborate on the idea of finding a planet that could potentially replace Earth? What factors would need to be considered in order to determine if a planet is suitable for human habitation? Are there any known exoplanets that exhibit characteristics similar to Earth, and if so, what are the challenges we would face in colonizing such a planet? Also, is it realistic to expect that we will find a suitable planet in the NEAR future, or is this more of a long-term goal?
