[Utah-astronomy] Question On Recently Discovered Planet

I have a question on the recently discovered Earth-Like 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. David Baxter baxman2@comcast.net
