Why do stars twinkle and planet do not ? |
|
Answer» The twinkling of stars is due to atmosphereric refraction of starlight. Since the stars are very distant, they seen point sized. When we see the stars their light entering in our eyes and hence eye flickers and the stars were twinkle.The planets are much closer to the earth and seen as extended source. Stars twinkle due to atmospheric refraction of light .stars are very far away so they considered as point sorces .when the light comimg from stars enter to the earth atmosphere it gets refracted.when the refracted light comes more towards us or reaches to our eyes it appears brighter and seem to be twinkling.Planets are larger and near the earth in comparison to stars ,they do not act as point source .there is no refraction from planets.thus there is no twinkling |
