Celestia Forums

I created a barycenter and an object (A) orbiting it. This works. I also placed another object (B) orbiting the barycenter. This works too. But when I'm trying to place a moon (C) around "B", it doesn't show at all. Celestia gives me all the info about that second moon, but there's nothing there. What's up ? Here are the definitions I'm using :

stc file :

Barycenter "Black Widow"
{
RA 6.054
Dec -72.057
Distance 13361
}


ssc file :

"A" "Black Widow"
{
Texture "Black Hole.jpg"
Emissive true
Radius 25
Oblateness 0.1

EllipticalOrbit
{
Period 1E12
SemiMajorAxis 1E-12
}
}

"B" "Black Widow"
{
Emissive true
Texture "Pulsar.jpg"
Radius 12

EllipticalOrbit
{
Period 9.7243327665E-7
SemiMajorAxis 2E-4
}
}

"C" "Black Widow/B"
{
Texture "Pulsar.jpg"
Emissive true
Radius 5

EllipticalOrbit
{
Period 0.05
SemiMajorAxis 70
}
}

Take note : there are no star in this system. Only a barycenter and three "planets". Why "C" isn't showing ?

Well, apparently, it's a limitation of Celestia : It has to be a star in the system. So I placed a small white dwarf around, and it solved my problem. A bit weird.
