Detailed explanation-1: -Photosphere-The photosphere is the deepest layer of the Sun that we can observe directly. It reaches from the surface visible at the center of the solar disk to about 250 miles (400 km) above that.
Detailed explanation-2: -The photosphere is the visible “surface” of the Sun.
Detailed explanation-3: -The boundary between the Sun’s interior and the solar atmosphere is called the photosphere. It is what we see as the visible surface of the Sun. The photosphere is not like the surface of a planet; even if you could tolerate the heat, you couldn’t stand on it.
Detailed explanation-4: -The photosphere is much brighter than the outer parts of the Sun’s atmosphere (the chromosphere and the corona), so regular photos of the Sun do not show the outer atmosphere.
