Physics Planets do not twinkle because Their distance from the earth does not change with time 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. They emit light of a constant intensity Their distance from the earth does not change with time 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. They emit light of a constant intensity ANSWER DOWNLOAD EXAMIANS APP
