Planet Temperatures?

Post #1by Slartibartfast » 05.01.2008, 01:37

How does Celestia calculate a planet's temperature? I went to great lengths to ensure my planets are in their goldilock's zones... yet their temps aren't right.

You can modify the albedo. This is a measure of how much energy planet reflects. An albedo of 1.0 means that it reflects 100% of the energy it gets, this will cause Celestia to render it as absolute zero. Setting an albedo of 0 makes it absorb all the energy, making rather higher temperatures. Assigning a negative albedo will make it absorb more.

Another temperature bug for planets (this'll be the third time I bring it up): Planets orbiting a barycentre are given a temperature of absolute zero, regardless of their distance from a star.
Current Setup:
Windows 7 64 bit. Celestia 1.6.0.
AMD Athlon Processor, 1.6 Ghz, 3 Gb RAM
ATI Radeon HD 3200 Graphics

Hungry,

Have you posted the bug to Celestia's Bug Tracker on SourceForge?
