In this case, it is expected that any habitable areas would be confined to the border region between the two extreme sides, generally referred to as the terminator line, since it is only here that temperatures might be suitable for liquid water to exist.
In this case, scientists think that any habitable areas on the planet, if they exist, would be confined to the border region between the two extreme sides, generally referred to as the terminator line. It is only here that temperatures might be suitable for liquid water to exist.
