CBSE · Class 10 · Science · The Human Eye and Colourful WorldWhy do planets not twinkle at night?
Step-by-Step Solution
Planets do not twinkle at night because they are much closer to the Earth compared to distant stars and can be considered as extended sources of light rather than point sources. A planet can be visualized as a collection of a large number of point-sized light sources. The total variation in the amount of light entering our eye from all the individual point sources averages out to zero, nullifying the twinkling effect entirely.
