Fun Fact! The atmosphere of the sun is hotter than tits surface.
Temperatures on the Sun's surface reach 6,000 Kelvin. However, this is far less than the atmosphere of the Sun. The chromosphere is a region of the atmosphere located above the Sun's surface, with temperatures reaching 100,000 K. That, however, is insignificant. The corona, which extends to a volume larger than the Sun itself, is an even more distant region. The corona can reach temperatures of one million degrees Celsius.
