    The resulting values can be divided by 10 to convert them into astronomical units (AU), resulting in the expression: a = 0.4 + 0.3 × 2 n . {\displaystyle a=0.4+0.3\times 2^{n}~.} For the far outer planets, beyond Saturn , each planet is predicted to be roughly twice as far from the Sun as the previous object.
