The solar corona is much cooler than the sun surface.

Tech science sun solar jets plasma one of the biggest mysteries of the sun is why its upper atmosphere also known as the corona is over 200 times hotter than its surface. She likens it to walking away from a campfire and feeling colder and colder until suddenly getting very hot. This solution to the coronal heating mystery was presented at a media briefing on april 28 2015. But the temperature at the sun s surface the source of that energy is a relatively balmy 5 500 degrees.

It s just weird says winebarger. Clear evidence now suggests that the intense heat of the sun s atmosphere depends on explosive bursts not continuous heating.
