Detailed Solution

The above statement is True.
The Planets are closer to the earth as compared to the stars. So, they can be treated as a collection of a large number of point-sized sources of light. Due to varying conditions of the atmosphere, the darkest part of the sparkling effect from one point source may be overlapped by the focused light from the point source of another region of the planet. So, the total amount of light entering the eye remains constant. This is the reason why planets don’t appear to be twinkling.
