ABC asteroid belt

[BradHann]

Never seen an asteroid belt around more than a single star before. Common? Rare?

 

[Zieman]

Medium rare at least.

Saw a double-star asteroid belt some time ago, thought it was odd at the time but apparently not odd enough to take a screenshot.

I'm guessing EDSM doesn't know how to handle these, since the belt isn't included here:

EDSM - Elite Dangerous Star Map

The Galactic Positioning System of Elite: Dangerous at your service.

It seems to show it around the E star.

 

[Orvidius]

I guess that's possible, but the screenshot of the system map has the E-star mostly out of frame, so we can't see if there's an actual E-ring.

 

[recrudesce]

Yeah, API shows only 1 belt:

      "belts": [
        {
          "name": "Iowhail PL-P b21-82 E A Belt",
          "type": "Metal Rich",
          "mass": 46804000000000,
          "innerRadius": 304740,
          "outerRadius": 1288800
        }
      ],

@op more info required !

I had another look at the sysmap and yes, there's another belt around the E star.

 

[recrudesce]

OK, then yeah, bug.

I guess we need to raise it with EDSM.

I did, I have one here.

I went back and took a view in the Orrery as well, it shows it clearly around the two stars B and C.

I have seen a few of them now, check the mass of the asteroid belt as well, if it is a proper asteroid belt around multiple stars it will show a very large mass compared to asteroid belts around single stars. The mass of this BC ring is 4 moon masses whereas most asteroid belts barely reach a single moon mass, most of them fractions of moon masses. I've seen so many I have stopped taking screenshots. I often check masses when I see one I think may be unusually large. The largest I think I have spotted so far was over 22 moon masses.

So I looked in the journal and noticed that E star has a sub-entry for Rings:

{ "timestamp":"2019-10-23T21:34:48Z", "event":"Scan", "ScanType":"AutoScan", "BodyName":"Iowhail PL-P b21-82 E", "BodyID":8, "Parents":[ {"Null":6}, {"Null":0} ], "StarSystem":"Iowhail PL-P b21-82", "SystemAddress":180960261127865, "DistanceFromArrivalLS":11710.060547, "StarType":"L", "Subclass":2, "StellarMass":0.152344, "Radius":201998096.000000, "AbsoluteMagnitude":12.545700, "Age_MY":12865, "SurfaceTemperature":1815.000000, "Luminosity":"V", "SemiMajorAxis":338887901184.000000, "Eccentricity":0.170402, "OrbitalInclination":2.160043, "Periapsis":319.526978, "OrbitalPeriod":356138304.000000, "RotationPeriod":96208.828125, "AxialTilt":0.000000, "Rings":[ { "Name":"Iowhail PL-P b21-82 E A Belt", "RingClass":"eRingClass_MetalRich", "MassMT":4.6804e+13, "InnerRad":3.0474e+08, "OuterRad":1.2888e+09 } ], "WasDiscovered":false, "WasMapped":false }

But neither A, B, nor C does. Nor is there a conglomerate for ABC. There is, however, a separate entry for each individual cluster in the ABC belt:

{ "timestamp":"2019-10-23T21:35:42Z", "event":"Scan", "ScanType":"AutoScan", "BodyName":"Iowhail PL-P b21-82 ABC A Belt Cluster 5", "BodyID":18, "Parents":[ {"Ring":13}, {"Null":1}, {"Null":0} ], "StarSystem":"Iowhail PL-P b21-82", "SystemAddress":180960261127865, "DistanceFromArrivalLS":604.516785, "WasDiscovered":false, "WasMapped":false }

It looks like the journal doesn't actually have an entry for the belt as a whole, so probably not much EDSM can do about this.

I would raise it as a bug then here: https://github.com/EDSM-NET/FrontEnd/issues
