Why do stars twinkle: Stars appear to twinkle

Stars appear to twinkle because the light from these distant objects passes through wobbly air in the atmosphere. The stars seem to twinkle in the night sky due to the effects of the Earth’s atmosphere. When starlight enters the atmosphere, it is affected by winds in the atmosphere and areas with different temperatures and densities. Stars twinkle due to the Earth’s atmosphere. As light from a star travels through the vacuum of space and enters our atmosphere, it encounters varying layers of air with different temperatures and densities. These layers cause the light to refract, or bend, in different directions. This refraction varies constantly due to atmospheric turbulence, making the star ’s light appear to flicker or ‘ twinkle ’ when observed from the ground. What makes stars appear to twinkle in the night sky, as seen from Earth? And why is it that stars twinkle , but planets do not?
