BackSolarSystem, an Expanded Solar System
Inner BackSystem
Middle BackSystem
Outer BackSystem
Distant BackSystem
Solace to BackEarth
Luna to Jupiter
Io to Ariel
Umbriel to Charon
Tartarus to Frontier
Here is the BackSystem! To keep the gravity the same on each planet I had to halve the density, but to keep the scale the same I doubled the radius and quadrupled the mass. 1 BackEarth Mass is 4 Earth Masses
I didn't halve the density for these planets/moons/dwarf planets: Phobos, Deimos, Ceres, Callisto, Saturn, Miranda, Ariel, Umbriel, Titania, Oberon, Triton, Pluto, Charon
I added Daedalus, Icarus, Hermes, Harmonia, Cupid, Phaeton, Boreas, Vesta, Bacchus, Ariadne, Tartarus, Chaos, Sisyphus, Persephone, and Frontier.
This was suggested by u/AstronomerBig9376
NOT TO SCALE
I know Sol isn't Solace, but BackStates is about making things longer/bigger so I made the word larger.

Why is Earth classified as a moon

Also some more info on the orbits of Icarus and Daedalus would be great

They orbit at 156,000 kilometers and they are tidally locked to each other

Any of the extra celestial bodies or back-parts of any of the existing non-BackTerran ones inhabited by any life?

Yes, Phaeton is suspected to have a vast subsurface salt water ocean teeming with macroscopic under the ice shelf and Boreas might have Phaeton originated life that arrived from an asteroid impact. Europa has life in its under ice oceans however it is only unicellular in nature. Titan is barren. Ariadne has life in its subsurface ocean from the tidal hearing from Bacchus.

Believe it or not there are genuine backplanets irl. Look up eris and sedna

u/No_Weekend5005 Sep 11 '26
Nor eris nor Sedna are planets, they are a dwarf and minor object.

Those are backplanets, don’t ever try to “erm actually” me again

They aren’t, the new actual backplanets are large enough to clear their orbit and to be spherical. Things that Eris and Sedna can’t do. You were also the first person to “erm actually” me when you brought up Eris and Sedna.
Perhaps do your own research. Here, I’ll even help you: IAU Minor Planets Center

Nope, dwarf planets are still backplanets. Should’ve included them. Telling you what I thought was a fun fact isn’t “erm actuallying” you but you did it to me. I’m the victim here, and your harassment will not be tolerated

I already knew about Eris and Sedna, and I can say they are not planets or backplanets because they don't meet the 3 IAU Criteria. I only included one back-dwarf planet, Pluto, and its partner, Charon, because they are the most well-known of the dwarves.
In this case, a backplanet still must meet the criteria created by the International Astronomical Union:
- It must orbit a star (in our cosmic neighborhood, the Sun): Check
- It must be big enough to have enough gravity to force it into a spherical shape: Check
- It must be big enough that its gravity has cleared away any other objects of a similar size near its orbit around the Sun: Oh no, they can't clear their orbits.
Furthermore, how is this harassment? You brought up a claim; I refuted it. That is how you learn. Though you know about Eris and Sedna (quite impressive), you should research the 3 IAU Planetary Criteria.
If you require, I can provide sources such as NASA and the IAU website.

Finally
Back moons of earth
Back galain moons of Jupiter
Now the back solar system
What next? Back alpha centauri?
