Expert Answer:

Planets don't appear to twinkle because they are much nearer to Earth than stars. The planets appear much larger to us, so the "twinkling" effect of refracted light is not nearly as noticeable as it is with stars, which are so far away they appear to be only pinpoints of light. However, if the Earth's atmosphere is particularly turbulent, or you are using a powerful telescope, you may notice the planets doing a little twinkling of their own.
