Q.11.    Explain why the planets do not twinkle.

Answers (1)

Planets do not twinkle the way stars do, the reason is that stars are so far away that they appear to be a point source of light on the sky, while planets have finite size and the size of a planet "averages out" the turbulent effects of the atmosphere.

Therefore, we see a relatively stable image to the eye. Hence, twinkling is not observed in planets.
