Planets do not twinkle because

• they emit light of a constant intensity
• Their distance from the earth does not change the  time
• They are very far away from the earth resulting in decrease in intensity of light
• They are nearer to earth and hemce we recieve a greater amount of light and, therefore minor variations in the intensity are not noticeable
