Question

star twinkle but we do not see the twinkling of planet why?​

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

Stars emit light but planets do not emit their own light therefore planets do not twinkle.
