I don't see any change whatsoever in Mercury's orbit even if I run max speed. Which is strange, because before the ephemerides patch, the perihelion and aphelion rotated around the sun at regular intervals. Which is the accurate one?

Look more carefully. Rotation rate is just 9,5 arcminutes per century, ie on a valid time span of the DE436 model (1000 years) it rotates for just 1,5°

I don't understand what you're saying. It's two million CE and the orbit hasn't visibly budged at all. I remember that at max speed (prepatch) it made a full rotation almost every second.

The DE436 ephemeris has a valid time span of 1100 years total (1550-2650). Outside of that span, you will not see the effects you're looking for.

Mouthwash, we have talked about this in this thread long before (and also in the Work in progress thread):

FastFourierTransform:Source of the post I've just saw the precession of Mercury's perihelion. It's beautifull. But the problem is that it uses the DE436 theory that goes from the year 1550 to the year 2560. After that it imediatelly stops. If VSOP87 is also implemented and has unlimited timespan, why we can't see further evolution of Mercury's orbit?

FastFourierTransform:Source of the post Precession of Mercury's perihelion: I saw it in SE and looks great, but only occurs from the year 1550 to the 2560. Considering this is a more or less periodic phenomena could you make the timespan for the precession bigger? In that way we could see further evolution of Mercury's orbit. It's a very small angle now and If one has to explain it to people they are not going to clearly see it if it is not with longer duration.

SpaceEngineer:Source of the post JPL ephemeris does not calculate that value directly, so it cannot be extrapolated above the end points of the simulation.

Ohhh, so it only shows the change for the period of time it's been recorded. What I saw before must have been a bug, because I definitely saw full rotations (it only showed at the two or three fastest speeds).

Nah, it's just your computer screen cracking from the stress of being so near a black hole.
(joke, please have mercy on me)

Oh, the black square around your monitor? I'm getting that too.

The fix for wrong Saturn rotation period (4h) is easy:

- extract SolarSys.sc from <SE folder>/data/catalogs/Catalogs0980.pak: it must be copied to this path:
<SE folder>/data/catalogs/planets/SolarSys.sc
- open it with notepad, find Saturn script, find RotationModel "IAU", and replace this line
RotationRate 1810.7939024 // degrees/day
with this one:
RotationRate 810.7939024 // degrees/day

It was just a minor typo.

I hope this is the right place to report a bug, didn't see a specific bug report thread, if not I do apologize, but I found a bug in the patch.  If I enable fisheye view after installing the patch, if background is enabled everything turns a pink hue, and whether or not background is enabled there are only a few small square "peepholes" on the screen where anything can be seen through.  The rest of the screen is just solid black (or pink if the view background option is ticked)

Spaceengineer any progress/update on VR support for space engine? Thanks!

[quote="MaxVelocity"]How to install patch pls?[/quote]



Just go to WinRar and choose 'Excract'. Choose Space Engine. You are done then.

Hello everyone! I've a problem about fix the Saturn rotation period, because i can't find the file SolarSys.sc and also i don't have the folder 'planets' in catalogs

Someone can help me ?
