star appear to be twinkling but planets do not twinkle . why ? explain why the colour of the clear sky during sunset appear red.
Answers
Every layer of Earth's atmosphere has air moving in different directions at different intensities. When light from stars passes through the atmosphere, it is bent due to refraction, which is why stars seem to twinkle when we stare at them. If viewed from outer space, you would not see the stars twinkling.
Stars twinkle because they’re so far away from Earth that when light from the stars passes through the atmosphere, it is bent countless times due to refraction, making it look like as if they were blinking. The sun doesn’t twinkle because it’s too close to Earth compared to other stars.
What makes a red sunset?
As the sun gets lower in the sky, its light is passing through more of the atmosphere to reach you. ... The sky appears red because small particles of dust, pollution, or other aerosols also scatter blue light, leaving more purely red and yellow light to go through the atmosphere.

Answer:
Light of the star is bent many times and in random directions as light is bent when it hits a change in density. This random refraction results in the star winking out - twinkling.
Planets are closer to Earth and so appear as tiny disks in our sky.
The light from these little disks is also refracted by Earth’s atmosphere, as it travels toward our eyes. Due to the planets’ apparent closeness to Earth, the light coming from these celestial bodies does not bend much due to Earth’s atmosphere. Also being not a point source but appearing as disks, they comprise of several point sources- lights of which are coming at the same time. So a deviation in light path of one point source can cancel with deviations of other and would average out to give rise to a steady shine. Therefore, the light coming from our solar system’s planets does not appear to twinkle like stars.
Explanation:
2.
it is because of According to Rayleigh''s law, the intensity of scattered light
