>>11258588>but I'm wondering why it's not naturally occuring, in our solar system, or in any solar system among planets.It is, but only for objects that didn’t form WITH the system originally, or one that did and has been perturbed by something outside of the system. A rogue planet flying through interstellar space could be caught by the Sun in a polar orbit, and planets in the solar system (or other objects like asteroids and comets) could get pulled into a polar orbit around the sun by other stars moving very close to the solar system below or above the plane of the ecliptic.
> Even when looking at galaxies, they form a "disc" shape, looking somewhat flat. Never seen an elliptical galaxy? There’s a LOT of them, they’re just not as “pretty” as spirals.
> What causes this?Centrifugal force during the formation of the system
>Why do galaxies have this disc shape, and not a spherical one?There are spherical galaxies, and even fucked up clumpy galaxies.
