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.
The thermosphere layer is called the thermal layer as it is the hottest layer of the atmospheric envelope . It is the fourth layer of the atmospheric envelope , The temperature of the thermosphere layer increases with a high rate as we go up until it reaches 1200 degree Celsius.
