Abstract
If Titius-Bode Law (TBL) was only a relation between three, four or even five planets, then we could call it a coincidence, but when it is true for seven planets, plus Ceres and Pluto (nine objects), there is definitely a reason for it. Here, we show that, probably, the existence of a standing and cosine wave packet in solar system, with the wavelength λ = 0.6 AU (AU represents the distance of Earth from the sun) and the phase constant ∅0=π/6, is the reason for TBL. In this article we obtain the equation of this wave packet. In this article we prove that without Solar System Wave Packet (SSWP), it is not possible to reach to the TBL from the protoplanetary disk of solar system. Here we show that the nebular theory (or nebular hypothesis) without SSWP theory is an incomplete theory.
