Gas giants with ginormous rings?

[DjVortex]

A very long time ago I remember going to a system (might have been a somewhat remote one, ie. outside the Bubble, but I can't remember for certain now), which was inhabited (as far as I remember) and there was a space port orbiting a gas giant, and said gas giant had an absolutely humongous set of rings. And I mean really, really big. Like the size of a small solar system. Extraordinarily unusual and rare.

For the life of me I cannot remember where this was. Does this ring a bell to anyone? Where could this be?

Are there more than one gas giant out there with astonishingly huge ring systems?

Yes!

Here is a list with large outer ring radius of various types of bodies, in fact from this the max outer radius of ring systems appear to be 211,480,000km as there are a number of bodies with this exact number as outer radius, not sure system or what station you were at with the ringed gas giant but there are indeed quite a few around.

Plaa Aescs BK-Q d5-60

I could recommend these two candidates:
In the system Plaa Aescs BK-Q d5-60 is a gas planet with an almost 27mill km ring

Or the system Plieloae YG-L c8-1, this ring is quite small, but due to the high orbital inclination of the only moon, you can really enjoy the ring from the surface of the Moon.

There appears to be a discrepancy with some of the data there:

Yeah that is odd, but that's not that unusual, it depends when the system was first visited and whether the data was originally hand reported (ie manually entered before eddn), that has led to some strange data getting in. In this case, if you check the system on EDSM, you will see there is no actual data in EDSM for this planet in EDSM. However Spansh does have data for this planet and it is incorrect in the spansh database, since ED Astrometrics pulls data from these sources it's not surprising it's incorrect. Someone scanning the system using a tool like EDDiscovery or EDMC that reports to EDDN should eventually see the error corrected.

It might not be coincidence that the value at the astrometrics site is 188450000, while the actual value is 188449, which is pretty much the same (rounded), but 1000-fold.

It's not at all a coincidence, some early reporters doing manual reporting often got the scale incorrect. For instance when I first started playing and exploring there were a number of planets with a reported radius of 20km in the then databases, now this is obviously incorrect, but in entering the data they entered 20 for bodies when it should have been 2,000 and etc. I flew around and corrected a lot of the obvious ones at the time, but there was a whole lot of errors, and probably still are in game, from the early manual reporting days.

Not a gas giant but a brown dwarf, however, EDO says it has "wide rings" and they seem to extend out to several light seconds but... how can you tell? The system map doesn't show "ring information" as it would for a planet's rings. EDO must be reading this from the journal somewhere, since it says it even before the system is scanned, but where in the journal, what does the journal info say?

Easy, click on another planet, click on planetary information then click back onto the brown dwarf, the composition and the ring orbit data will be available.

Edit, just the ring orbit data will be available

Ah thanks. I rebooted the game too for good measure.

Sadly no hotspots...

Incidentally, does anyone know the biggest Gas Giant that has been found, and the smallest brown dwarf? How close in size are they?

The smalest Brown Dwarf has 0,0223SR or 15,514.11km HR 318
The bigest Gas Giant has a radius of 90,000km Sharur
