Topic about calculation factors (days - years, km - AU, etc.)

Post #1by EarthMoon » 09.11.2023, 14:46

How many days are one Earth year in Celestia? I found many definitions in the web: 365, 365.25, 365.2425, 365.24219052, 365.2563604167, 365.259635864, but which of them is the one Celestia uses?

For values in ssc files where the unit is years, 1 year is exactly 365.25 days. Celestia's date calculation is of course more accurate than this.

If SSC's EllipticalOrbit SemiMajorAxis units are AU, how many km are one AU?

1 AU is 149597870.7 km, searching Celestia's codebase confirms that this is the value used.
