Twinkling of stars

Planets, moon and sun  look much bigger in size than the stars because they are situated at much smaller distances. Each planet can be supposed to be made up of a number of point sources.

 When some of the point sources appear brighter, others appear dimmer. Therefore overall brightness of the planet or moon or sun remains same always and they do not appear to twinkle.
