Abstract
Pluto, Ceres and all planets of Solar system except Neptune, with a high approximation, follow a rule called Titius-Bode rule or Bode rule, which can by no means be considered as a stochastic event. This rule shows that the distance of planets from the sun in Solar system is regulated. Here, I prove that the existence of a standing and cosine wave packet, with the wavelength λ = 0.6 AU (AU represents the distance of Earth from the Sun) and the phase constant ∅=π/6, in solar system is the reason for Bode rule. And moreover, I prove that this huge wave packet belongs to the sun. Bode rule does not predict the distance of Neptune from the Sun but, this article is able to give us the distance of Neptune. Based on this article, Quantum mechanics will enter into a new stage.
