It sure as heck ain't solid.

Tom Brosz — 12/7/2005 5:01:18 AM (archived)

The photosphere is almost a vacuum. I've looked up some numbers and references, and the short version is that temperature goes up a lot faster than pressure does as you head toward the middle of the sun.

I'm still no expert on solar physics, but so far I haven't seen any zones in the sun where pressure and temperature would combine to allow solids to form.
