The masses are smaller. It's the surface gravity that remain similar, demanding MUCH greater density. Kerbal is about 1/10 of the size of the Earth, but have the same surface gravity. To achieve that, you also need to have 10 times the density. The average density of the Earth being 5,527 g/cm^3. This imply that Kerbal's density should be 55.25 g/cm^3. Osmium, the most dense element have a density of 22,587 g/cm^3. So, Kerbal's density is more than twice that of the densest element.

There is a mod that enables N-body gravity in KSP and makes celestial bodies also simulate N-body physics. It has to reconfigure the Jool system to avoid the moons clipping through eachother and slinging into interstellar space

IIRC from some earlier similar experiments someone did some years ago, a big part of the problem with Jool's moons is that the orbital phases of the inner moons are wrong so that they're not actually in a Laplace resonance like Jupiter's Galilean moons are. Could try just fixing that and see if it helps.

the kerbol system is more stable than my future

I was thinking you should have tried to put Laythe, Val, and Tylo on a 1:2:4 resonance like Io, Europa, and Ganymede. with maybe bop and pol a lot farther out. although their extreme densities might still prevent that

@strcmdrbookwyrm

4 ай бұрын

Funny that you mention that because Laythe, Val, and Tylo are actually in the Laplace (1:2:4) resonance in the base game. I'm pretty sure the resonance is what ends up throwing Val out of the system, and that you'd need to retune the mass and orbital radius of each moon quite a bit to make the resonance work.

Well what a little jewel of a channel i just discovered. Keep up the good work! 😊

@TheEpicDragonCat

4 ай бұрын

Thank you! Will do!

yeah the Big issue with Jool is not just that the moons are too close together. Gas giants tend to have a mass ratio with their moons. Which usually means the moons are around 10000 times less massive than their parents. There are exceptions like Saturn's moon Titan, but even then Saturn is 4000 times more massive than titan. The moons of Jool over step these boundries by a LOT So therefore they (especially vall and Tylo) compete for gravitational influence quite a bit. In fact, just as Duna and Ike's center of mass is not exactly at the center of Duna, The center of mass between Tylo and Jool is Also not in the middle of the system, which further destabilises the whole thing! So really, the only way your fixing the Jool system is either if you give it Far smaller moons, Or, if you want to keep the original moons, Turn jool into essentially a brown dwarf (but KSP sized) and only then you try to make the moons orbit further out.

@avandorhu-3389

There was a mod that converted Jool into a brown dwarf. The mod's name was...well, brown dwarf jool. Sadly, it hasn't been updated in a while. So, while i've tested it and it still works fine with the latest versions, it is kinda buggy and the textures on Jool are not quite up to date. It is a shame. Would love to see how it would look with the modern textures of jool. Hopefully someone will update or make another version of that mod sometime. As per the question on Laythe, I don't know for certain. My guess is that since vall is much less massive, and Tylo is further out, it doesn't effect Laythe quite as much. But again, i'm not really sure.

Ok, one correction, Mercury wouldn't be able to hold onto a moon unless it was something like a VERY close captured asteroid in a circular orbit, but Venus's orbit is almost as far out as Earth's, in theory it would be able to hold a decent sized moon somewhat closer in than ours. The reason it doesn't have one is simply because one didn't form there and it never captured anything.

Yeah, I was talking to someone else about this, and I think Jool is too lightweight. It needs to have its gravity increased. So, I’m definitely going to return to this at some point to get it right.

@TheEpicDragonCat Sigma Dimensions allows for whatever scale you want, including 10x scale.

From some experimentation I did in Universe Sandbox, without figuring out stable orbital resonance configurations (just "place and go"), I got good results keeping the orbital periods to at least 4 times the period of the next innermost object (so if Laythe orbits in 1 day, Vall would have to be on a 4 day or longer orbit, Tylo on a 16 day or longer orbit, etc). In case you're wondering, I was trying to figure out if Jupiter could capture the Earth and the Moon and have the Moon be stable around the Earth while the Earth is stable around Jupiter in a scenario like Fritz Leiber's "A Pail of Air".

I love that Solarballs reference. I have US2 and I love your content!

Weird that your results are different to what happens with Principia and the vanilla ksp system. What's supposed to happen is that bop gets ejected.

But Principia doesn't have spheres of influence, it calculates gravity using Newtonian physics so in theory they should come to the same result, which leads me to believe that this kerbol system in universe sandbox is different than the kerbol system in ksp.

@TheEpicDragonCat

I also just realized that Jool may be less dense in Universe Sandbox as the KSP wiki lists it as having 7.8m/s^2 gravity. Principia may have upped that value to make it more accurate, but not sure.

I think they uploaded an updated version but I'm not sure, because some objects seem broken due to the update.

As well as what people have said about density (The planets have been given similar realistic mass but much smaller volume so are all super dense), the Jool system could be improved by making the moons have resonant orbits with each other. If two moons are interacting they should be put in a resonance where one has an even number and the other has an odd number (like 5:4 or 3:2) and normally that makes the gravitational pulls and pushes even out over time.

@TheEpicDragonCat

4 ай бұрын

Good point

Don't forget, they said that Kerbol is 1/10th scale. so they should all be 10x the distances... It might actually work then.

I might try and do something similar but with the Juno System

Try to put the planets in resonating orbits around Kerbol and the moons around their host planets. Orbital periods with 1:2, 1:3, 1:4, 2:3, 3:4, ... relationship. Those usually tend to me stable.

What a fun video! I think KSP is best modeled with tiny planets and ordinary densities, but the gravitational constant is scaled up by a factor of ten. Can Universe Sandbox do that?

No, it’s just a weird artifact of how I cut and spliced in the post commentary 😂

I think the real problem with Jool’s moons is that they’re just way too massive (when the 1/10 scale is accounted for) compared to the real Galilean moons. Like if they were half or a fourth of their ingame mass I could see the system being much more stable, at the expense of Tylo losing its main gameplay challenge

Maybe work the Jool system into a Laplace resonance?

The Jool system would be a lot more stable if you fit the orbits into a resonance. I'm not sure how well UniverseSim deals with resonances though...

I thought maybe KSP, like other stylized space games, used a different G constant value to make it less difficult to play. Thought do not quote me on this, it’s an easy enough experiment to run in the game.

You should play outer wilds one day, it's a pretty fun space game! (and maybe try checking if the ow solar system is unstable too...)

@@TheEpicDragonCat as you discovered, they're not very stable otherwise. Moons larger than asteroid size are almost all either tidally locked if they're the only big one, or in an orbital resonance with other moons since the orbital resonance is asymptotically stable. The issue with moons like Minimus and Gilly that are so far out on circular orbits is that in an N body simulation (as opposed to patched conics) it doesn't take very much of a tug to put them on one of the manifolds that leads out through L1 or L2 after a couple of orbits. Gilly's orbit might already be on one of the outgoing manifolds even without any tugging.
