1.2 Preorganic Beginning Mass Ejections.png

  Planet Oxidi, newly formed, rotates at an unusually high speed, causing it to flatten in it's hot liquid state. Much of the equatorial material is thrown out due to inertia, some of which forms the moon.


Planet Oxidi has just formed, spinning unusually quickly. Due to it's hot, fluid consistency at the surface, the planet is almost disc-shaped and not at all spherical. It is also extremely unstable, with bulges periodically appearing at the equator, growing over time and eventually sloughing off into space. It eventually lost over 60% of it's material this way, going from being around 2.5 times the mass of Earth to just over 1.2 times by the end of the Early Preorganic, ending in a shape closer resembling a slightly compressed sphere.   Although it's rotation speed continued to remain faster than Earth at a similar stage in formation, it lost a lot of it's momentum compared with when it was much larger and had more equatorial mass.   Many of the ejected blobs, once cooled into asteroids and planetoids, were never seen by the planet again, or would only be seen during rare passes having picked up orbit around the star. However a few became the planet's sattelites. The largest satellite consumed most of the smaller ones and much of the molten rock debris surrounding the planet, becoming the moon. The impacts from acreting material from smaller ejections slowed the moon's rotation and it's speed of travel around the planet. It also changed the angle of the orbital plane away from near-perfect equatorial, and made the orbit slightly eccentric. Thus, the moon can be seen at different hemispheres on the planet and may also appear smaller or larger, both depending on the moon's point in the orbit cycle.
