Question

Why do planets not twinkle?

Answer 1

Planets, just like the Sun, do not twinkle. Planets are also closer to the Earth than those distant stars, so planets appear larger in comparison. Due to the planets’ apparent closeness to Earth, the light coming from these celestial bodies does not bend much due to Earth’s atmosphere. Therefore, the light coming from our solar system’s planets does not appear to twinkle like stars.
