Question

Why do stars twinkle and planets do not twinkle?

Answer 1

It is because planets are closer to earth than stars so the light coming through them to atmosphere does not bend much. Stars are very far and from far we can assume them as point source of light. So when their light travels towards earth they undergo multiple deviations and bends in the space and also in the earth's atmosphere. Due to this light's intensity becomes very low and our eyes capture these lights with low intensity and due low light intensity our eyes don't see stars clearly and so they appear to be twinkling in the sky

Answer 2

HI

⏺️Stars appear as point-sized sources of light since they are distant objects.The physical conditions of the atmosphere,through which the starlight travels,are not stationary.Therefore the apparent position of the star fluctuates and the amount of starlight entering the eye flickers.Hence, the stars appear to twinkle.

⏺️Planets are seen as extended sources of light since they are closer to the earth.It can be considered to be made up of large number of point-sized sources.The variation in the amount of light entering our eye from all the individual point-sized sources average out to zero.This nullifies the twinkling effect. As a result, planets do not twinkle.
