Is blue lava hotter than the sun?

Lava is indeed very hot, reaching temperatures of 2,200° F or more. But even lava can't hold a candle to the sun! At its surface (called the photosphere), the sun's temperature is a whopping 10,000° F! That's about five times hotter than the hottest lava on Earth.

The color of lava depends on the temperature of the flow as well as the chemical composition and any impurities that are in the liquid rock. Colors can include black, red, gray, brown and tan, metallic sliver, pink, and green.
