Why do stars twinkle but planets do not ???? |
|
Answer» Stars twinkle because they appear as tiny pinpoints as seen from Earth, even through telescopes. Planets don\'t twinkle because they are closer, and thus appear larger in our sky, as tiny disks instead of pinpoints. The planets are much closer to the earth and are thus seen extended sources. If we consider a planet as a collection of a large number of point sized source of light the total variation in the amount of light entering our eye from all the individual point sized sources will average out to zero thereby nullifying the twinkling effect. |
