Mention the factor on which scattering of light depends. Why does the sky appear dark in space?

(N/A) The scattering of light depends on the size of the particles present in the atmosphere. Particles like smoke,tiny water droplets,suspended dust particles,and air molecules scatter light of different wavelengths.
In space,there is no atmosphere,which means there are no air molecules or other particles to scatter sunlight.
Since no light is scattered towards the observer's eyes in space,the sky appears dark.
