I am successfull running the fully internet updated 64 bit version of Stellarium on Windows 7 64 bit. I would like to pose the following questions for those in the know about Stellarium:
I know that I have access to the extra solar system observation point. I also know that I can set my observation
"planet" point to the sun. I have done this. I have also specified the "north pole" of the sun.
-Is there a way to turn the simulated rotation of the sun off? Besides which, does the sun rotate anyway (I'm guessing it will), and does Stellarium do this accurately?
I have noticed two things about turning on the Exoplanets button.
-Is it true that not all of the presently known exoplanets have been entered into Stellarium updates, or not? There are one or two really big clumps of them.
-The other thing is that these exoplanets havn't been given orbital paths around their stars (suns). They also don't exist under the observation points button. Are there plans to change these?
What mathematics is used to model the orbital paths of each of the solar planets around the sun? Are displacement points taken from force and mass considerations, along with taken initial positions and speeds, or not?
It appears that a "general" path is stipulated first with corrections later. Is that general path a self-meeting bezier curve in 3D?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
-Is there a way to turn the simulated rotation of the sun off?
You can set rot_periode=0 for the Sun
Besides which, does the sun rotate anyway (I'm guessing it will), and does Stellarium do this accurately?
It's problematic for all areas of Sun, because Sun has different periods for different areas. Stellarium use for model a middle latitudes period of rotation.
-Is it true that not all of the presently known exoplanets have been entered into Stellarium updates, or not? There are one or two really big clumps of them.
Yes, we use the list of confirmed exoplanets in Stellarium from the exoplanets.org website.
-The other thing is that these exoplanets havn't been given orbital paths around their stars (suns). They also don't exist under the observation points button. Are there plans to change these?
No plans for it, because Stellarium are not simulator. You can use Celestia for simulating orbital paths.
What mathematics is used to model the orbital paths of each of the solar planets around the sun?
None of the questions deal particularly with 64bit issues.
-Is there a way to turn the simulated rotation of the sun off?
You can set rot_periode=0 for the Sun
You must edit this value in your C:\Users\YOU\AppData\Roaming\Stellarium\data\ssystem.ini.

Stellarium use for model a middle latitudes period of rotation.
Gassy objects, i.e. Sun, Jupiter, Saturn, Uranus, Neptune, are modeled as simple spheres with rigid rotation and rigid texture. There is no sunspot simulation, coronal holes, filaments, prominences or other activity simulated on the sun, and no change in the cloud cover of Jupiter or Saturn or any other planet. And there is no weather simulation on Titan. Nor on Mars, nor on Earth. No active volcanoes on Io or Earth. No polar lights.
It is an open-source project however. If Stellarium otherwise fulfills 95% of your requirements, you can add your required functionality however.
-Is it true that not all of the presently known exoplanets have been entered into

If you are familiar with exoplanet issues, you will notice that the objects in one "clump" are all labeled Kepler... Guess why.
-The other thing is that these exoplanets havn't been given orbital paths around
their stars (suns). They also don't exist under the observation points button. Are
there plans to change these?
No plans for it, because Stellarium are not simulator. You can use Celestia for
simulating orbital paths.
Most of the exoplanets have not been imaged yet, but only exist as gravitational hints. Details on orbits are too vague to start any modelling yet. And there are no plans to do that in Stellarium.

No, Stellarium does not solve of the gravitational task for all bodies of Solar system.
No, it's not a Bezier curves :)

Should be easy enough to find in our wiki. Private answer again: VSOP87, ELP2000-82B.
