why do stars twinkle,?
Answers
Answer:
Stars do not really twinkle, they just appear to twinkle when seen from the surface of Earth. The stars twinkle in the night sky because of the effects of our atmosphere. When starlight enters our atmosphere it is affected by winds in the atmosphere and by areas with different temperatures and densities
Answer:
Due to the atmospheric refraction
Explanation:
The stars twinkle because the light coming from it act as a point source and due to the atmospheric refraction it's fluctuates at observer eye.
They don't actually twinkle.
The light coming from it passes different levels of the atmosphere which have different optical density and light passes from rarer to denser medium they moves toward normal and this cause fluctuation in observer eyes and the observer thinks that star is twinkling.
