Answer:  Planets are bright and they don't twinkle

Mercury, Venus, Mars, Jupiter, and Saturn are usually brighter than the stars in their immediate neighborhood. Planets also shine with a steady light. Stars, especially on a windy night, will appear to twinkle very rapidly, while a planet in the same area of the sky will twinkle very slowly. The specialized word used by astronomers for twinkling is scintillation.
