The zigs and zags of light from a planetary disk cancel each other out, and that’s why planets appear to shine steadily. Compared to stars, the planets are much closer to Earth, due to which the shift in atmospheric refraction is smaller. Scintillation affects planets, too. This is what gives out a twinkling effect. The speed at which the light travels changes depending on the medium and therefore this bending occurs. The starlight, on entering the earth's atmosphere, undergoes refraction continuously before it reaches the earth. Venus is the brightest light nearer to the center.
