I present a review of the two types of planets and the orbital characteristics of their satellites and evaluate evolutionary explanations for them. While the naturalistic theories may explain certain features, other features require a number of well-timed catastrophic events. To have so many of these events is very improbable. The evolutionary theory cannot explain certain aspects of solar system bodies. To date, there have been few comprehensive proposals for a creationary model of the solar system. The invocation of design must be carefully thought through.
