Sounds like a stupidly easy question to find out with a quick internet search, but it’s not.

I don’t want to know the average surface temperature, or the average ocean surface water temperature, or read another article about climate change.
But that’s all I found in the past hour.

I’d like to know the average temperature of all molecules that comprise earth, or a best guess scientific estimate.

    I have no exact answer but the earth’s mantle makes up approximately 84% of its volume and has temperatures ranging from 500k to 4200k. So I would estimate the average temperature to be in the upper bounds of that range.

      So that figure is just the mantle, no core or surface? I agree it would be near the top, if not above. The heat from the core would easily offset the loss of heat from including the surface.

        Yeah, the volume of earth is <1% the crust, ~84% the mantle and ~15% the core. So the surface temperature has basically no impact on average temperature.
