Physics Planets do not twinkle because They are nearer to earth and hence we receive a greater amount of light. Their distance from the earth does not change with time They emit light of a constant intensity They are very far away from the earth resulting in decrease in intensity of light They are nearer to earth and hence we receive a greater amount of light. Their distance from the earth does not change with time They emit light of a constant intensity They are very far away from the earth resulting in decrease in intensity of light ANSWER DOWNLOAD EXAMIANS APP
