This summarizes my take on what happens to begin GGarciaWow's system. Things to do: Add shadows Put back the time counter Give the planets better textures Maybe add faces/expressions There was an unnamed planet, closer to Daios, that was ejected. Daios formed last of all planets and enjoyed a lack of chaos during its birth. Jubilee was 4th last to form and also had stability, except for losing its moon once Hanakura arrived. An unnamed planet formed 2nd to last and collided with Sessias early on. Sessias was the first inner planet to form and 5th to form overall. They collided with the aforementioned unnamed planet early, which stripped their mantle and left them mostly metal. Much of the material remained bound to the earth in an extensive retrograde system of loose moons. The biggest and nearest ones were larger than Pluto, although they quickly decayed into a huge ring system. As each farther and smaller moon falls in and joins the ring, the ring becomes fainter and fainter, and by 10 Ga, it will be fainter than Neptune's. An unnamed Earth-size planetesimal was 3rd to form and collided with Terminus early on. Terminus was second to form. Collided with the Earth-sized planetesimal and migrated inward with its 2 moons. It and its inner moon ended up habitable. N/39582B was third to form and was slingshotted in after a hit-and-run collision with N/39582C. It formed 2 moons from the surviving protolunar disc some time after the encounter. Aether was the first planet to form. It's the only native gas giant and the largest planet in the system. It was what allowed Hakaruna to enter the system in the first place. It originally had 5 moons, but all but 1 were collided, ejected, or torn into a ring. N/39582C was fourth to form and was slingshotted out by the hit-and-run collision with N/39582B. They lost whatever moons they had during this. They were in a stable orbit out there until Hakaruna arrived,arend is slowly pulling it outward to a point of stability at 13 AU. Hakaruna is a rogue planet that joined just 175 Ma after the system formed. Their orbit was slowed down by Aether and circularized by interacting with comets and other icy bodies in their region. Their orbit is only 8 degrees off the main orbital plane, because they cleared out their orbit too fast to bring that to 0. They had a moon, but tore it into a huge ring system shortly after arrival which is surviving a long time because of shepherd moons and because it's distant from the star.
Black outline = terrestrial Colored outline = gaseous The blue planets all have surface water, except for N/39582 B and C. (The two outer terrestrial planets) The addition of Hakaruna into the system created an LHB that gave the inner planets (and Honos, Terminus's inner moon) much larger amounts of water than they already had, and gave Asthetia a dusty ring.
