The scale/mass of the sun is just fascinating. It takes ~500,000 years for a photon released in the fusion process to escape the core. That's just how dense the core is that a photon gets bounced around that much. The fact that the outer layer (corona up to 3,500,000°F is so much hotter than the surface(photosphere around 10000°F) that is on top of the core (around 27,000,000°F) is just another one of those weird to appreciate as well.
