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