Celestial bodies in In Extremis’ universe of Omneutta are slightly different from what we are used to seeing from planets in our solar system. Omneuttian celestial bodies are modeled after terrestrial planets like Earth or Mars. However, instead of continents that rest on a semi-solid mantle, the continents float through space around a star-core. This also means that Omneuttian celestial bodies do not have large oceans.
Star-Planets take the place of stars in Omneuttia, as they generate light far enough to be seen far across the sky, whether night or day. The star-core inside star-planets is much larger and closer to the landmasses that orbit around it. Because of this, star-planets are uninhabitable to mortals.
Planet-Stars are the other major bodies of Omneuttia. They can be found in orbit around the larger star-planets, as part of Asterisms that usually bear the name of the star-planet being orbited. The star-cores of these are smaller and as a result the Sentient Species along with other Omneuttian flora and fauna have flourished. Some star-cores among Planet-Stars are larger or smaller than others, leading to differences in average temperatures between planet-stars.
Not every celestial body in Omneuttia fits into either a Planet-Star or Star-Planet category.
Planet-Stars that are not in orbit around a star-planet are referred to as Planemos, planets that do not orbit a larger object. Some planemos in Omneuttia have developed binary or multiple orbits with other planemos.
Continemos are continents or landmasses that do not orbit a star-core. Due to the lack of heat they usually feature cold and harsh locales. If formed from a dense enough material, the change in gravity from a planet-star’s landmass may not be noticeable.
