Question

stars appear to be twinkling but planets do not Twinkle why explain why the colour of the sky during day appears blue and during sunset appears red​

Answer 1

Answer:

When a ray of light travels from one medium to another it ‘bends’. This phenomenon is referred to as refraction. If it travels from a rare medium to a dense medium, it bends towards the normal and if it travels from a dense medium to a rarer medium, it bends away from the normal. The speed through which it travels changes depending on the medium and therefore this bending occurs.

Planets do not twinkle like stars because the distance between the planets and the earth is not far when compared to the distance between the stars and the earth. As the distance is less, the refraction of light won’t be much for planets. Thus, planets do not twinkle.
