Genis Tria

A solar system in Oltesos. It has one sun and nine planets.

The sun. It's a K-type or something, but none of the planets are tidally locked.

The closest planet to the sun, and one of the few inhabitable spaces. Lucerifus has two moons: Hellas and Lunas.

The second planet, and roughly the same size as Lucerifus. Ontalius is covered in a thick green atmosphere, it is nonetheless inhabitable, although humans may have a tough time with the atmospheric pressure. It has one moon, Mirrus.

The third planet, and the smallest gas planet. It's bright enough to be seen on Lucerifus with the naked eye, as the sun reflects off the yellow gasses very easily. Has two moons: Psez and Kor.

The fourth and largest planet in Genis Tria. A gas planet with many moons and satellites, the five largest of these being Maxoria, Larenia, Medinia, Sumia, and Minelia.

The fifth planet, and another gas planet. Kalirifus features a series of rings, it has several moons, the three biggest being Forian, Nian, and Javian.

The sixth planet, and the second largest gas planet. A ball of radioactive gas, it has exactly five satellites: Toz, Thez, Fiz, Sevz, and Elez.

A binary system with two small terrestrial planets. Uninhabitable as they both lack an atmosphere and are too far away from the sun, and so are too cold to sustain life. The only moon they have is each other.

The ninth planet, it's so far from the sun that for a long time, no one was sure if it really existed until after the Great Wars, when it and its two micro-satellites (Junim and Herim) were confirmed.

• Lucerifus was originally Luciferus and may or may not have been what I was going for, but it was changed to not just be Lucifer.
  • Moons are named after Helios and Luna
• Ontalius is made up, but its moon's name comes from “mirror”
• Desacrius is from “desecrate”, while its moons together make “corpses”
  • Always imagined its atmosphere to be mostly sulfur.
• Superius is from “superior”
  • The moons are, respectively, “maximum”, “large”, “medium”, “small”, and “minimum”
• Kalifirus is also made up. Assuming the moons are also made up
• Radionus is, perhaps surprisingly, named after “radium”
  • Satellites are the first five prime numbers
• Geminus is named after “Gemini” while I don't remember what Doriscus is
• Kripplius is not based off “cripple”. Its orbiting asteroids are named after “Juno” and “Hera”
