Question

why does the star twinkle at night but planet do not twinkle

Answer 1

Dear Student

A star appears like a point even when we see it from a telescope, while a planet looks like a disc. A stars has its own light, so when it enters the Earth's atmosphere, it gets reflected by different obstructions. As a result, it twinkles. But since the planets are near, the light reflected by them comes to us directly. Hence, they do not twinkle.
