Why Is The Sun Yellow?

Sun is mainly made up of gasses like helium, hydrogen and other elements in small amounts like carbon, neon, sulphur, oxygen, magnesium, nickel, chromium and calcium. The surface of the sun has a temperature of approximately 5780K giving it a white color but it often appears yellow when we look from the earth due to the atmospheric scattering of light.

When the sunlight coming towards the earth passes through the earth’s atmosphere, it scatters blue light because of which the sky looks blue and it is left with red color which looks yellow to us. During sunset in the west, more blue light is scattered than normal which makes the sun appear more dark orange or red. It can be said that when we look at the sun from earth, it appears yellowish in color but if we move to the space there will a slight change of color and also its brightness.

Some people believe the appearance of the sun to be only the interpretation of human eye as the sunlight strikes our retina visual cortex and processes finally telling the brain that the light is yellow in color.

The photosensitive cells in our eyes detect the color, they are usually known as cones and some animals don’t have these cones. It is possible that the animals can see the light as somewhat grey but this not yet been proved and we are unsure about it. Their retinas have black and white rods which are sensitive to high light.
