Wrong orbital period

[Bosi]

When I watch Solar system with 100000x speed ratio. All planets (including Earth) make one complete orbit about the Sun for ~1-2 moths only ...
Why? What I do wrong?

Do you mean that you leave Celestia running for several months of real time?

When Celestia fails, what year is shown in the upper right corner?

Celestia is not designed to work past the year 2 000 000 000. It has numeric problems when its values get too large.

I mean any year in the upper right corner, e.g present year 2009, no matter which...
For example,
Let take Jupiter....
( I will upload video)...

Sorry for russian planet names... It's Jupiter runs there... If it runs correct than time goes too slow...
It time is corrent than Jupiter runs too fast...
Have a look please...

Jupiter's period is 11.8 years = 11.8 * 365.25 * 24 * 60 * 60 seconds
= 3.724 x 10^8 seconds

3.724x10^8 / 100000 = 3.724x10^3 seconds
so Jupiter should take about an hour to go around the sun
when Celestia is running 100000 x faster
That *is* what happens when I run Celestia on my computer.

I do not know why the planets are moving so fast on your computer.
What Addons do you have installed?
I am wondering if one of them has changed all of the orbits so they run 1000x as fast.

What version of Celestia are you running? v1.4.1? v1.5.1? V1.6.0rc1? svn?
What operating system is your computer running? Windows XP? Linux? (What distribution?)

[Bosi]

Celestia v1.5.1 , (which has been downloaded yesterday)
OS: Windows XP Professional (Service Pack 2)
CPU: Intel Core 2 Duo E6300 1.86GHz , DDR-II DIMM 2Gb

None.

I am beginner in Celestia, so no .celx .cel scripts had been changed.

Hello,

There is no problem with your computer.

This is because you are in sync orbit around the sun.
Just type "F" to follow it.

I didn't see any differential rotation in the solar system. The inner and outer planets seemed to rotate around the sun as if they were like spokes on a wheel. So something is wrong. Can you capture a cel url and post it here? I can't remember how this is done in Windows. I think there may be a menu item in the upper left under the "File" menu or item that say copy url or something like that.

Jogad is right. You must have typed "y" when the Sun was selected. This locked your position to the rotation of the Sun. The equator rotates every 25 days or so and the polar latitudes rotate every 36 days or so. At the distance you were at, you were rotating around the solarsystem at warp speed to stay in sync with the Sun's rotation.

"F" works, thanks!
