Stars are very far away compared to the planets, so we can observe  the refraction of their light by earth's atmosphere whose refractive index changes as temperature changes, as TWINKLE.

Also the reflected light from planets also undergo refraction but they are comparatively nearer to us, so the twinkle is not discernible.
