Inner Moons List
- Thread starter Shnyrik
- Start date
To my great shame I haven't yet mentioned Ocularis Coelum (aka Mylaifa AA-A h786) in this thread, despite I've been in that system a couple of times.
Time to correct this injustice

I'll just post it right here to show, how awesome Eol Prou QI-B e1809 is
The body with shepherd moons is water world #8.

And one more system, reported by cmdr. Mooing: Eorgh Prou TI-S d4-648 body # 8 -- Helium-rich gas giant.
And one more nice-looking system reported by cmdr. Dr. Nagi: Kyloanns TF-D d13-60 body #1 -- Gas giant with water-based life. This time -- with a ringed outer ammonia moon.

Wait a minute that's not a shepherd moon or does that system have another? I didn't check all moons... Stunning sight nonetheless.And one more nice-looking system reported by cmdr. Dr. Nagi: Kyloanns TF-D d13-60 body #1 -- Gas giant with water-based life. This time -- with a ringed outer ammonia moon.
Well, that would be rather unfortunate. Can you check orrery, please?
According to EDSM data it looks very-very-very much like that at least moon #1a should within the gap in GG's rings.
UPD. I've also checked it on the shepherd moons list and the first three moons (from #1a to #1c) appear to be in there.

Can do when I'm home, if I don't forget it
And one more nice-looking ring system: Eoch Pruae EH-U d3-3099 body #3 -- Class I gas giant, reported by cmdr. Junagu.
And while I'm slowly making my way to Col 107 Sector UY-Q b34-4, we have one more system reported by cmdr. Starsong: Eoch Blao AA-A h65 body #1 -- class K star with 28,6 million km. metal rich ring.

Well, I'm here and I'm afraid, I have bad news: Col 107 Sector UY-Q b34-4 body #AB 3, despite being a planet with the largest currently known ring, is visually completely unremarkable. It's outer ring is not only invisible, but also even too sparse to be obstacle for a ship in supercruise mode, so it renders on the map, but is actually not there physically. Moreover, it is so dark in the system, that I had to "lit" the inner ring with dss probes to see it.
The next ring with radius of around 40 million km. is not very far, maybe I'll be more lucky this time

In the meanwhile cmdr. bluefoxxy reports a gas giant with a large nice-looking ring and shepherd moons in FLYIEDGE DG-N D7-56.

And I just don't have time to type, because cmdr. Gut Rumble reports one more planet -- a water giant -- with extra large rings and shepherd moons: Preia Phoea gc-t d4-76 body #A 13
There is a study on the question of rings visibility, made by cmdr. Gromsch. It shows, that there definitely is a connection between ring's density and visibility: the higher the density is, the more is the probability that the ring would be visible.
I've made a table of the confirmed planets with shepherd moons and sorted them by the density of the rings. And we can see, that invisible rings all have density of less than 46 tons* of material per km3, while the visible ones tend to have density of more than 46.
* Unless I lost a few zeros in the calculations
However, we can't just say, that all sparse rings are invisible, for we have a few examples of the contrary (I've marked them in the table by red font).
For instance, the overall density of the outer ring of Cúpla Iontach is very low, but the material is condensed in a collection of several thin dense and visible separate rings.
The same is true for one of the most beautiful rings I've seen -- the outer ring of the Poseidon's Fury
And for The Rejected Child
And, to be completely honest, for all known visible large and sparse rings of planets with shepherd moons:
On the other hand dense rings seem to be more often rendered as one piece. Here are some examples from the end of the table:
What do we have in the end.
1) We can calculate the ring's density from the EDSM data and if that density is above some margin, it is very highly likely that the system would provide us with some nice views
2) If you see a large ring made of several thin concentric rings -- it's overall density would probably be low, and if the ring is rendered in one piece, it is probably dense (have no idea how can that be of any practical use )
3) If the density of the ring is below the margin, there still actually is a chance that the ring is visible, however I don't know how we can guesstimate it from the list without flying and checking

I've checked two more systems with large rings with the same result: they are too sparse to be visible.
Col 89 Sector NZ-L b10-1 body #ABC 5 is so dark, that even the inner ring is barely visible and 35,6MKm outer ring is seen only on the map.
Synuefuae RY-S d3-0 body #AB 1 is on the contrary rather bright, however that didn't help much: I still didn't manage to find any trace of it's 36,5 MKm outer ring.

Have no idea how I came across the address of that system, for it is definitely not in the list of shepherd moons. But still here it is -- a nice-looking "false positive" in Swoilz IT-O d7-77. It has three rings with a gap among them and a relatively close moon.
But nope, not this time

In game graphics & system map show 3 rings, the system map even lists A, B & C, but for the orrery & DSS the C ring doesn't exist as a separate entity.
