The night side will be cold - Mercury is a good example as it has a very long "day". Have a look at [this document](http://www.sciops.esa.int/SB-general/Projects/BepiColombo-OLD/BepiColomboSTRep/chapter4fin.pdf) as an example.

Suppose a terrestrial planet with no atmosphere is tidally locked and very near the star like a hot Jupiter.

Is the far side still very cold or would crust would conduct heat from the near side to far side?
