   Mesh    "asteroid.cms"
   Radius  0.03


   EllipticalOrbit {
      Epoch        2454000.5   
      Period             4.1731 
      SemiMajorAxis      2.5919832060534       
      Eccentricity       0.729996700971176

Red,

Grant has provided the contents of an SSC catalog file. Copy and paste the text into a file named (for example) qm111.ssc in your Celestia/extras/ directory. Then start Celestia and enjoy.
