The Parker Solar Probe will make its closest approach yet to the Sun

I don't know if I'm shocked or not shocked that the temperature is 2500F 4 million miles away from the Sun. Part of me expected it to be much much hotter than that, but I guess it is 4 million miles. Considering we are 90 million miles away, and the temperature still gets up to 120F on the Earth, maybe that makes sense?

Depends on the object receiving the heat. Walk outside in bearfoot in summer. You will soon notice some surfaces are way hotter than others. This depends on how efficiently heat can transfer. Convection, radiation, conduction I think are the 3 ways.

The air temp is heated by the sun, those surfaces then the atmosphere is preventing heat escaping. A lot going into that 120F!

That is why things like climate change and urban heat islands don't need a closer sun.
