Application in Astronomy NOTE.. 'P' signifies orbital period in years. Inner AU­ (9/4p) = P ­ (3/2p) Outer AU­ (3/2p) = P ­ (1/p) Keplers AU ­ (3/2) = P Main Equations Defining Equation [( p­(9/4p).Ln30) - F]­(2p/3) = 20p Primary Equation [( AU(9/4p).Ln30) - F]­(2p/3) = Outer AU Secondary Equation [( AU(9/4p).Ln30) - F + F2]­(2p/3) = Outer AU Venus Equation { [1 - V(9/4p) ] / [V(9/4p) - 0.506756171] } -V = 0.00
