Five planets, one barycenter

I noticed something curious on a more recent find. Here's how the system map looked:


Looking at the orbit lines, the two pairs of planets orbit two barycenters, and those two centers orbit a third one. So it turns out that the arrangement is important, although maybe it was just me who didn't notice this sooner. Looking at Allitnil's five-body example, the orbit lines show this as well: three gas giants orbiting one barycenter, two gas giants orbiting another, with both barycenters orbiting a third one. As it turns out then, mine might be the only known example of five planets around one barycenter.

But the thing I find the best is that the arrangements can be even more varied and complex than I originally thought. Frontir gib orrery plox
 
Your example isn't actually 5 planets around one barycentre though. It is two planets orbiting around one barycentre that are then in orbit with a third around a second barycentre. Those 3 are then in orbit with the 4th around a 3rd barycentre and then all 4 in orbit with a 5th around a 4th barycentre!

At least, that's how I read it.
 
Hm, I don't know. Having looked at the orbit lines in-game, it certainly looked like they were all orbiting the same one. However, this was me eyeballing it, and it might turn out that they aren't, and the different centers are just very close together. On your example, it's obvious that the pair of two and the pair of three have plenty different, but in such cases, without an orrery, it might be hard to tell.

You know, on second thought, I'd actually prefer it if it really were five planets around four barycenters. Why? Because that would give a more complex arrangement and a more varied "dance" of bodies than five-one would. Would be great to actually be able to see it in action.

I agree with Allitnil's assessment. I see it being like a baby mobile like this: http://1.bp.blogspot.com/_U-C7Zd4gM2I/S7tp0fVOUKI/AAAAAAAAAjw/7wkYGTz9o0Y/s1600/bluefish_ml00.jpg

And here's an example that I found a while ago:

@ ASC: Hey, that's a pretty good example. Thanks for posting it! (And the fishies too :D) Looks like I was wrong, and so is the thread title then.
Say, your screenshot is pretty old: are any of those planets landable, and do they look different now? I should visit it sometime too, it's in a good place, but I'm quite far from it now.
 
I never thought to check before, but sadly, nothing in that system is landable.

I do remember that the bodies were quite far apart - and indeed the closest pair have an orbital period of some 110 days.
 
I vaguely recall there having been some posts about such, but can't seem to find them. So, I came across five planets all orbiting the same barycenter, around a single class K star, in a mass code C system. I'll post the system name once I sell the data (will probably be at least a couple of weeks), but in the meantime, here's how they all look:

Quite far from the star. Thanks to the distance and all having quite thin pure nitrogen atmospheres, they are all quite cold; the sixth planet out is actually considerably warmer, thanks to having a thick atmosphere (99.9% nitrogen, 0.07% methane, 1154.13 atm, 141 K.)
Pity that none of these are landable, but I think it's a cool find nonetheless.

Great find Marx.

Here is the one I've found in April. La Vita Nuova

It is similar in the configuration as the one you found. Just with different planets.

Five planets and one barycenter is quite rare.

Congrats.

So the new (WIP-)orrery makes it certain, the thread title was wrong. There are pairs of barycenters:

But to be honest, the orbits look better this way than if they were all around one barycenter. A pity you can't see them in motion.

Well, good thing I found this before Chapter Four, because it would have ended up undiscovered after.

That is beautiful - very interesting to see it laid out like that. Have you considered adding it to the Elite Galaxy Online database and making the Orrery there? They have an Orrery which actually functions like one, in that it moves and allows time dilation.
 
Yep, it's there, but I couldn't complete the hierarchial editor required for EGO's orrery. Then I forgot about it, due to hardware errors I had at the time. Will have to take another look at it.
 
Hm, actually, could I ask anybody who might be nearby to swing to the system and make a screenshot of the spectrum graph? To see if there's any way it looks different than usual or not - as such, if there would have been any way to spot a rare configuration like this without having to scan everything.
