This thread is for discussing minor bodies (read: anything besides the four major planets and their moons) in the outer Solar system, with the exception of comets which are discussed here.



There were two big discoveries announced today in the realm of the outer Solar system.

First up is the discovery of a new inner Oort cloud object, only the second one ever discovered (the first being Sedna).

http://www.space.com/25218-d....ge.html

Here it is for SE. Add the script to the planet catalog of your choice (KuiperBelt.sc is best).

Code
Asteroid    "2012 VP113"
{
      ParentBody "Sol"
      AsterType  "Centaur"
      Radius      320
      Albedo      0.1
      AbsMagn     4.1
      SlopeParam  0.15
      Orbit
      {
       Epoch            2456800.5
       MeanMotion       0.0002149
       SemiMajorAxis    276.0078196
       Eccentricity     0.7106887
       Inclination      24.01461
       AscendingNode    90.89192
       ArgOfPericenter  291.14923
       MeanAnomaly      3.066
      }
}



Second, and perhaps more significant, is the announcement of rings discovered around Chariklo, the largest known centaur. The structure of the rings suggests that Chariklo has at least one moon.



http://www.eso.org/public/news/eso1410/
http://www.space.com/25225-asteroid-rings-discovery-video-images.html

Here it is for SE. Overwrite the existing script in KuiperBeltSmall.sc with the script below (if you want to go the extra step, move the entire entry to KuiperBelt.sc which is a more suitable home). Then, download the rings texture to your textures/planets folder.



Code
Asteroid    "Chariklo/(10199) Chariklo"
{
      ParentBody "Sol"
      AsterType  "Centaur"
      Radius      129.3
      Albedo      0.06
      Color     ( 0.710 0.631 0.604 )
      AbsMagn     6.6
      SlopeParam  0.15
      Orbit
      {
       Epoch            2456401
       MeanMotion       0.015787
       SemiMajorAxis    15.7375
       Eccentricity     0.170708
       Inclination      23.4067
       AscendingNode    300.392
       ArgOfPericenter  241.399
       MeanAnomaly      54.0798
      }
           
      Rings
      {
       Texture        "chariklo_rings.*"
       InnerRadius  390
       OuterRadius     409
      }
}

Rings texture download

EDIT: For some reason it seems to direct to a Russian download page rather than English (YandexDisk has been overhauled recently, and for the worse in my opinion). Just click the button that says Скачать

EDIT 2: There's also a language selector in the bottom-right smile

Ringed asteroids? Nature is always far away from expectations. When on SE?

I just added this one to SE, and I'm sure SpaceEngineer will add ringed asteroids to SE soon smile (though they would have to be very rare).

I've always been fascinated by the outer Solar system, so I am glad it has a seperate thread. I imagine asteroids could have rings only if they are very massive.

Where can I find it? I'm searching 11019, Chariklo's number, in the object search, but it's saying "Object not found". I've placed the code where you told us to place it. (Move it from KuiperBeltSmall to KuiperBelt)

phenomenalx, simply type in "Chariklo", or look at the very top of the list - (11019) Chariklo is among the first entries smile
In SE, minor planet numbers are in parentheses, I'm not sure why but that's how it's done. And the planet script above contains the name of the object, so you know from that exactly how to find it:

"Chariklo/(10199) Chariklo"

Different names for an object are separated by slashes.

Interesting idea!

I once tried to add aurora to a star, hoping that would make for some interesting-looking prominence-type features, given the right settings.

I couldn't get it to work, though.

Although addings rings around a black hole or neutron star may not be very realistic (from what I know), it might look really cool. Well, you can't add rings around the star itself but perhaps you can make a planet around that star/black hole/neutron star with a Semi-Major axis of 0, and then you give that planet rings that appear outside of the star so that it looks like the star has rings.





I will be inactive on this forum for the time being. Might come back eventually

so just thinking about that new dwarf world discovered in the outer solar system 2012 vp113 and when it will be added it seems like a cool body man the sun can sure hold a lot of stuff in orbit
