Detailed explanation-1: -The visible surface of the sun, or the photosphere, is around 6, 000 degrees Celsius (11, 000 degrees Fahrenheit). But a few thousand kilometers above it – a small distance when we consider the size of the sun – the solar atmosphere, also called the corona, is hundreds of times hotter.
Detailed explanation-2: -“It is very confusing why the solar corona is farther away from the sun’s core, but is so much hotter, ‘’ says University of California, Berkeley space sciences researcher Jia Huang. The solar surface lingers around 10, 000 degrees Fahrenheit, while the thin corona can get as hot as 2 million degrees.
Detailed explanation-3: -Jim Klimchuk, a solar scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, explained that the new evidence supports a theory that the sun’s corona is heated by tiny explosions called nanoflares.
