While the photosphere hovers around 5,800 kelvin, the temperature of the chromosphere varies between 4,500 K and 20,000 K. Even though itâs more distant from the center of the Sun, the chromosphere is hotter than the photosphere.he photosphere is the region of the Sun that we see. It measures an average temperature of almost 5,800 kelvin and produces the visible radiation. This is the point where photons generated inside the Sun can finally leap out into space. The chromosphere measures just 2,000 km, and itâs just outside the photosphere.
By mass the composition of the sun is 75 percent hydrogen and 25 percent helium. Various metals make up less than 0.1 percent of the mass of the sun. The temperature of the sunâs surface is about 10,340 degrees Fahrenheit (5,726 degrees Celsius).
