Don't forget to include a hot, molten core and our current atmosphere in this calculation!

Do not forget to include the hot, molten core and our current atmosphere. We're not talking about removing the sun, just stopping the solar energy reaching the earth.

There would be no Earth, but for the Sun and its energy.

"stopping the sun energy from reaching us", and "removing the sun" amount to the same, as far as the heat is concerned.
basically the Earth would go to very low temperatures, a few degrees about the absolute zero.
the molten core is all very nice but is not going to save the day at all - at best it is going to make a difference of a few degrees above absolute zero.
now of course an advanced civilisation could bury itself into the ground, and by going deep enough it could keep itself warm, melt ice to produce water, etc.

The hot molten core would have no effect in warming the earth's temperature. There wouldn't be even a volcanic explosion since most eruptions happen due to the Sun's gravity.
and, the earth's energy comes from the Sun mainly. If there would be no sun, we wouldn't be revolving throughout the Solar System.

Good question. The obvious answer is 0 Kelvin, but that isn't right. The core is hot. So if you take into account the R-value of the ground between the surface and the core, you might be able to come up with an approximation.
Additional details:
Ah. I see you've just added in the core temperature.

I don't think it is possible to get 0K temperature anywhere.The surface temperature may be near to the temperature of Pluto,around 40K,since Pluto receives very very little sunlight.The earth's crust provides a pretty good insulation against the heat from the core,and earth is not very volcanic either.So the heat from the core may not matter that much(think about the ice-age when the Dinosaurs were wiped away,just because the dust emanating from a meteoric impact had blocked the sunlight).

I think around 1K. All our heat comes from solar energy, directly or indirectly. Without it the Earth would be the same temperature as the rest of the universe.

I guess it will be at least -4 Celsius, which is the feezing point of water? My reason for this guess is that 78 % of the earth's surface is covered by water.

about 4 degrees Kelvin

temperature of earth depends on the solar energy...and there is no other planet or object in our universe which emit energy.the temperature of earth would be freezing.

zero and here was me thinking of going for solar energy must have a rethink
