But there are a few big bugs here. First of all, how can future humans make a planet about the size of the earth? Even if it is made out, it can't be so close. You must know that the tidal force caused by mutual gravitation will tear up the entire planet. Of course, there is also a possibility, provided that:
1. The masses of the two planets are exactly the same, or there is only a very small difference
. 2. The two are at the stable Lagrangian point of the other.
But in that case, the distance between the two is definitely greater than the distance between the earth and the moon. It's mostly, at least not as close as the last shot looked. (Welcome to discuss~~~)
