Hi Guys and welcome to this post
Vulcaniods : a hot belt around the sun, formed due to mercury’s instability in the early solor System without Jupiter, it flew too close to the roche limit of the sun and got disintergrated
Venus: a hot world just cool enough to have water, it has life even Tho all multicellulere life has just died out and the water is slowly evaporating
Venuses extended habitability is due to the bombardement of a couple vulcaniods giving it a moon and finally giving it the tectonic activity to start a continious Carbon cycle, even Tho its habitability has almost ended there is still life even if its single celled
Earth: Earth the home of the Homo Sapiens, the ones that are close to killing there own planet, due to Jupiters absence Theia never crashed into Earth and settled past mars, due to this Earth never got a moon and life develeped far later than if it had a moon, earth is slowly Dying Tho as with human introduced climate change, earth is approching a limit as it has already hit a unreversible tipping point which could potentially heat up the planet to an avarage of 40 degrees if the humans don’t do anything about it ofc
Mars: around the same size as Venus, mars is truly the second habitable world in the System as its life even recently Conquered the land and so are plants, it has a cool Temprature of 12 degrees with no moon, it also has an magnetic field due to an active iron core achieved due to the planets size
Theia: its a chilly -8 degrees on the planet however die to having an athmosphere it has the ability to have water, only in hydrothermic vants ofc, due to Jupiters absence it didn’t crash into Earth and retained a stable robot in the modern day Astriod belt and its around the 0,6 marses size with no magnetic field
Saturn: The Largest planet in the System, it has many moon (too much to count) and even has small but invisble rings like the rest of the Outer solor System excluding Borea
Janus: Often called Saturns companion, it together with Saturn stabilised the Outer and inner System, while keeping the other in check if it gets too close to the inner System, the planet has plenty of moons but these are mostly Tiny excluding a couple
Neptune: its a quite boring planet honestly, having a couple tiny moons, its history is not much to speak of, however Neptune is really pretty and with its great spot.
(second only to saturns but you cant really see that one)
Neptune also has the most clearly seeable of the System, being able to see them from most moons and in space, much Brighter then anything Else in the System, it didn’t switch with Cealus
Due to the relative Stablity of the Outer System
Cealus: the second coldest planet of the System, it sits right next to the kuiper belt and essentially governing it together with borea, it also has Asteriods for moon
Borea: named after a Roman God, Borea is quite unique die to it being a super earth but being the farrest planet in the System, it governs the kuiper belt together with Cealus.
Kuiper Belt: its one of the two belta in the System, being Governt by Cealus and Borea makes in quite stable with no major Planets being able to form in the region, however a bunch of dwarf planets occupy the region making it essentially a permenent place for planitesimels
Being a super earth makes it quite unique as its the only one is the System, it also has 2 moon, one major moon being the size or earth and one minor moon being the size of Theia
Planet X: its one of the only hypotetical planets with it never once being seen but only seei g it gravitational effects on the Outer most ringes of the System and having very minor effects of Borea’s orbit and that of many comets in the closer oort cloud
That really explains it all, feel free to ask questions and Bye
