Photosphere

Photosphere

Literally, sphere of light, the photosphere is the visible surface of the Sun.

It should be noted that when the surface is said there is no reference, in this case, to a solid surface, since the photosphere is formed by a gas layer.

Almost all the light that we receive from the Sun comes from the photosphere, although the source of energy is much lower, in the solar core. The photosphere has a thickness of approximately 300 km. and average temperatures of 6,000 degrees.
