Question

why do stars twinkle but planets don't ?​

Answer 1

Answer:

Unlike stars, planets don't twinkle. Stars are so distant that they appear as pinpoints of light in the night sky, even when viewed through a telescope. Because all the light is coming from a single point, its path is highly susceptible to atmospheric interference (i.e. their light is easily diffracted).

Answer 2

This is because stars are celestial bodies that produce their own light and that’s why for us it is visible that stars produce their own light while this is not so in the case of planets
