Temperature -1k?

Post #1by Angry Space Goat » 16.02.2005, 19:38

I have a gas giant in close orbit to a large star. However, the "temperature" reading is at -1k. Shouldn't it be a couple of hundred kelvins in the opposite direction?

Maybe.
But you'll have to provide the STC and SSC definitions that you're using for anyone to double check.

It's in orbit around Sigma Taurus.

Code: Select all

"Sanguis" "Sigma Taurus"
{
   Texture "Sanguis.*"   
   Color [ 1.0 0.2 0.2 ]
   Radius 83279.9
   Oblateness 0.0121

   Atmosphere {
      Height 100
      Lower [ 1.00 0.30 0.00 ]
      Upper [ 2.00 0.00 0.20 ]
      Sky [ 1.0 0.5 0.0 ]
      Sunset [ 1.5 1.5 0.5 ]
   }

   EllipticalOrbit {   
      Period            0.7000
      SemiMajorAxis     0.7500

The star name "Sigma Taurus" is not defined in Celestia. ("SIG1 Tau" and "SIG2 Tau" are defined, however.)

Please provide the STC file that you created for it.

If, for example, your planet is orbiting inside the star, I can imagine Celestia getting very confused, although I haven't tested that configuration.

Change the Albedo value to something a lot lower ,try 0.1.Not necessarily accurate but it should do the job,Jestr

It's not specifically defined as Sigma Taurus, but can be selected by typing it as such.

That worked fine. It now reads at 619k - thank you.
