Gaia’s history(brief and only the important bits): (Inner system, near Meca) During the Sun’s early life, Gaia would be formed as a result of the clumping of gas and the collisions of planetesimals. It would’ve been extremely volatile, and it would’ve had an extremely spread out ring made of gas and rock. Over time due to the gravitational influences of the sun and other planets, it would’ve been flung out of the inner solar system. During this journey is when it began to collide with a few large icy planetesimals that remained from the system’s initial formation. (Inner system near the Goldilocks zone) Over time these further collisions resulted in the creation of its two rings, its moon, and the existence of water on the planet. Now, on its journey to the outer system Gaia and Erthe both interacted with each other, this lead to Gaia flinging Erthe into the Goldilocks zone, and Gaia’s course being shifted a noticeable amount. (outer system) At this point in Gaia’s journey it would’ve started receiving the last bit of real heat from Sol, as it began to slowly cool down and life started to evolve. This cooling is still happening although Gaia is still much hotter and moist than Erthe due to its thicker, reflective outer atmosphere, and tidal heating from its three moons. This heat is also what fuels Gaia’s frequent storms and weather events. (Rings) During Gaia’s traversal through the outer system Gaia’s gravitational pull brought in multiple bodies of ice, and rock. These bodies would contribute to the formation of Gaia’s three moons and two rings. One of rings a circumpolar ring, is actively dissipating and “falling” towards the equator due to the planet’s equatorial bulge.

The body that was mostly responsible for ejecting Gaia into outer orbit was Cumora. For a few centuries they would pass each other and slightly alter each other’s rotation speed or trajectory. However they eventually got a bit too close and Cumora’s gravity threw Gaia off course, and then Gaia and Erthe got too close and Gaia threw Erthe into the Goldilocks zone like I previously stated. Cumora would also eventually be thrown into the outer system after a close interaction with Anula This description is genuine slop I might redo it later. Also, if you need clarification about certain things, just ask me.
(Moons) (Mann’s moon) Stats: Density: 2.53 Radius: 2,920 mi Mass: 1.02M Diameter: 5,840 miles Gravity: 1.87Gs Atmospheric density: 1.64 atm Atmospheric makeup: 94% nitrogen 4.1% oxygen 0.9% trace gasses 1% methane Chance of life: 13% (Brief history) It is believed Mann started out as a small water world after the initial explosive phase of Sol’s creation had ended. It would’ve orbited inside the outer Goldilocks zone around where Serenara presently resides. It would’ve likely stayed in this position for a few million years, with it possibly harboring life. However, once Gaia began its journey into the outer system its gravitational influence ejected Mann further out of the inner system. During this ejection, Mann cooled a considerable amount and collided with other bodies of rock and ice. Now, eventually Mann settled into an orbital path around where Trianus is modern day. However due to a collision with another planetoid Mann would cross paths with Gaia again. And this time Gaia’s gravitational pull would reel in Mann and lead it into Gaia’s outer orbit. And when it was initially captured by Gaia it actually stretched out a bit as a result of getting a bit too close. However it was ejected outwards before it could reach the Roche limit and it currently sits comfortably in Gaia’s outer orbit. (Miller’s moon) Stats: Density: 0.99 Radius: 3,958 mi Mass: 0.99M Gravity: 0.99gs Atmospheric density: 1.40 atm Diameter: 7,916 mi Atmospheric makeup: 55.5% Nitrogen 15% oxygen 20%carbon dioxide 8% water vapor 1.5% trace gasses Chance of life: 67% (Brief history) Miller began as a frozen protoplanet in the outer system. It would remain in a relatively stable orbit until it interacted with a younger Trianus. This interaction would lead to Trianus’ gravitational influence pulling Miller into a temporary eccentric orbit. The tidal heating and stretching effects from this event led to an increase of geological activity on Miller. Thermal vents would begin to open up under the planet’s large ocean. This allowed for the generation of an electromagnetic field on the forming planet, as a result of activity from the now active molten core. Eventually, the gas giant of Anula would cross paths with Trianus. Anula’s gravitational influence would eject Miller into the inner system, while causing short lived tidal stretching. Once in the inner solar system, Miller’s outer ocean would thaw out. This allowed for the creation of a weather system, as heat from Sol allowed for water actually being able to evaporate. With Miller occasionally crossing paths with bodies of gas and minerals. Allowing for more elements and gasses to enter Miller’s atmosphere. Now, after a while of Miller retaining a stable orbit around Sol. Along with a decently thick and reflective atmosphere. Miller would encounter Gaia during the super earth’s journey to the outer system. With Miller being pulled into Gaia’s orbit after a few close encounters. Currently, Miller is in a stable orbit around Gaia, with a large rotating storm around 9.54 million sq miles raging in its south. mass, radius, speed around the sun, density, diameter (Edmund’s moon) Stats: Atmospheric density: 1atm Gravity: 1.1gs Diameter: 6,793 mi Atmospheric makeup: 15% oxygen 5% carbon dioxide 70% nitrogen 7% water vapor 3% trace gasses Mass: 0.81M Radius: 3,396.5 mi Density: 1.28 (Brief history) Edmund’s started out as protoplanet in the inner system. Although, through a complex and random set of events, Anula and Edmund would cross paths. Anula’s gravitational pull would then reel in Edmund and keep it as one of its moons. And it would remain in a stable orbit with Anula until Anula crossed paths with Cumora. When the two crossed paths, their gravitational fields interacted with each other and altered their courses. During this interaction Edmund was thrown out of Anula’s orbit by Cumora, and launched into the outer system where it would be caught by Gaia.
