Stars closer to the horizon appear to twinkle more than stars that are overhead - this is because the light of stars near the horizon has to travel through more air than the light of stars overhead and so is subject to more refraction. Also, planets do not usually twinkle, because they are so close to us; they appear big enough that the twinkling is not noticeable

The planet is nearer to the earth. So the intensity of light is more provide. So the planet do not usally twinkling.

I am not agree with above all answers. The basic difference between stars and planets is. A star has its own light (Our SUN also one of the star). But a planet has no light of its own. It shines by reflecting the light of the sun.

Planets have no light. It just reflect light. Move Over, the Planets are closer to us. Stars have some tiny dust particulars so that it looks like twinkle. Stars are more far away from us.
