Explain why the planets do not twinkle?
Answers
Explanation:
Planets are much closer to the earth and are seen as extended sources. So, a planet may be considered as a collection of a large number of point-sized light sources. Although light coming from individual point-sized sources flickers but the total amount of light entering our eye from all the individual point-sized sources average out to be constant. Thereby, planets appear equally bright and there is no twinkling of planets.
Explanation:
As Planets can be considered as a collection of a large number of point-size sources of light, Planets do not twinkle because they appear larger in size than the stars as they are relatively closer to earth. The different parts of these planets produce either brighter or dimmer effect in such a way that the average of brighter and dimmer effect is zero. Hence, the twinkling effects of the planets are nullified and they do not twinkle.
