If the wandering earth really reaches Centauri, is it still a livable planet?
In recent years, many so-called super earths have been found in other galaxies, all of which are heavier than the earth, but not more than 10 times the mass of the earth. They have a thick atmosphere and are more suitable for life, so they are considered as the most powerful candidates for livable planets. For example, this planet, code-named HD40307g, is 42 light years away from the Earth and 93 million kilometers away from its star, so the temperature of this planet is probably higher than that of the Earth, but the temperature of the star HD40307g is lower than that of the Earth, so it is very suitable for human habitation.
Besides suitable stars and livable zones, it is also important to have a massive satellite. If there were no moon, the earth would still turn, but it would turn like a top and keep shaking, far less than a top. This will probably lead to the disappearance of the four seasons, the earth's climate will become very bad, there will be a big periodic change every hundreds of thousands of years, and it will also lead to the phenomenon of extreme day or night, which is not conducive to the evolution of intelligent life.
Red dwarfs like proxima centauri or TRAPPIST- 1 are usually the main targets for finding exoplanets, because they are the lowest temperature, lowest mass and most common stars in galaxies. Because they are cold and dim, their planets need to move in closer orbits for liquid water to exist.
