1 / 25

Planets do not twinkle because:

they are very far away from the earth resulting in decrease in intensity of light

they emit light of a constant intensity

they are nearer to earth and hence we receive a greater amount of light and, therefore minor variations in the intensity are not noticeable

their distance from the earth does not change with time
