If the planet has the same face towards its star, it would always be light on that half of the planet and dark on the other side. Its day (one revolution on its axis would be the same as its year (one orbit around its star), 14 earth days. I suspect that it would be cold on the dark side of the planet.

It is suppose to orbit its sun once every 14 Earth days. It is also suppose to have the same face to its sun, as it orbits it. That would mean on average that its daytime would be 7 Earth days, and its nightime would be 7 Earth days. On the daytime side, temperatures are comparable to Earth-like springtime temperatures. But how cold would the planet get during its nightime period? I realize that temperatures could vary by latitude. Sincerely, J.
