If one observes that the stars are twinkling significantly then, his seeing is bad (i.e., there is significant atmospheric distortion).
Large celestial bodies known as stars are primarily composed of hydrogen and helium and generate light and heat in their centers from churning nuclear forges. The other stars we can see in the sky are all light-years away from Earth, excluding our sun.
The planets, stars, moons, and any other naturally occurring objects in space are collectively referred to as celestial bodies or heavenly bodies.
The view of the rings beyond is distorted by light that is refracted, or bent, as it passes through the planet's upper atmosphere.
