What is the temperature between the earth and sun?

The difference of surface temperatures is ##6000^o C (Sun) -14^o C (Earth)##.

Sun's surface temperature is nearly ##6000^o C##. However, Sun's

Corona (atmosphere) temperature might be in ##millions ^o C##. Sun's

core temperature might be about 15 ##million^o C##.

In contrast, Earth's average surface temperature is about ##14^o C##,

with a record range ##[-89^o C - 71^o C]##, nearly.

Earth's core temperature might be close to Sun's surface

temperature. .
