I think temperature on earth would eventually drop to a few kelvin. The earth’s heat and heat generated by the moon’s gravity stretching the planet would increase that, initially, but I doubt it would be over 100 kelvin. That’s not cold or even cold cold, but cold³. If there still would be oceans, they would be a mix of nitrogen and oxygen.

I’m not sure living on it would be much easier than living in space. You would have better radiation protection and more raw materials, but staying warm might be harder.

I think air pressure (the weight of air above us at sea-level) compresses the air sufficiently for it to reach a temperature much greater than you would expect, e.g around negative 20 degrees Celsius.

(This figure needs verification, I'm going from memory).

But earth would still be radiating out heat, would it? If so, where would the energy come from to maintain that temperature?
