How Can Planetary Movements Affect Time and Illumination on an Inhabited Planet?

[QUOTE="snorkack, post: 6824579, member: 436348"] One thing that counts for both stability of system and basic lighting is orbital inclinations. Note how everything that orbits in inner solar system does so close to ecliptic. With two significant exceptions. One is inner satellites of Uranus and inner (i. e. all) satellites of Pluto, which orbit near primary equator instead. Note how they are very far from Sun, but fairly near their primary. And the other is long period comets. In contrast, short period comets orbit near ecliptic even when, like Halley Comet, they do so in retrograde direction. The reason is that large inclination orbits are perturbed far more strongly than low inclination ones. [/QUOTE]
