History of Solar System formation and evolution hypotheses full of hydrogen and helium gas and exchange of angular momentum between giant planets and the particles in the protoplanetary disc. The detailed features of the planets are another problem. The solar nebula hypothesis predicts that all planets will form exactly in the ecliptic plane. Instead, the orbits of the classical planets have various (but small) inclinations with respect to the ecliptic. Furthermore, for the gas giants it is predicted that their rotations and moon systems will also not be inclined with respect to the ecliptic plane. However, most gas giants have substantial axial tilts with respect to the ecliptic,
Planets and habitats of the Night's Dawn trilogy habitat to be germinated, after Eden. A floating habitat on Atlantis, captured by the possessed before being destroyed by Laton to stop them spreading to other habitats. A habitat orbiting Murora, in the Lalonde system. Habitat orbiting a gas giant of the Ross 154 system, the same primary as Felicity's. It was the first Edenist extra-Solar habitat. Orbits Saturn. One of the two Voidhawk bases. Orbits Saturn.
