What is the approximate surface temperature of the sun

The approximate surface temperature of the sun is 5,778 degrees Fahrenheit. 

The Sun's approximate surface temperature is 5,778 Kelvins, though it is 9,940.73 degrees fahrenheit.

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
