Rylix System Development

[MKruer]

I probably overlooked it, but have you tried putting the problematic planets in resonant orbits? (orbital period ratios like 1:2 or 2:3 etc)

No I havent Yet, but I will this weekend. I was just testing to see how my original system would react.

Once you've got your planets stabilised, it might also be worthwhile making sure your asteroid belts are stable. Gravity simulator has options to create several bodies on random orbits.

[MKruer]

Well it looks like I got a system that is fully stable or at least stable for over 50,000 years. Because I have 2 heavy weights in the outer system Gigus and Roubemon, all of the outer planets need to have almost perfectly circular orbits with a standardized osculation. Unless someone can find orbits that are closer in AU and still work I guess these are my new numbers.

*Based upon Roubemon

About the only reason why I am classifying Fridiga and Distare as planets is because they are too large, and too dense to be KBO?€™s and were probably inner planet ejected by Gigus sometime in the past, and Roubemon pulled them into circular orbits, or something to that affect.

So now that I have a working system, I guess I need to get back to making textures for all the planets or updating them. Most of them will not change based upon what I have written about the planets, but one is going to be difficult and that is Vilox. Vilox went from being a Mercury type planet to the core of a planet and I am not sure what type of texture to use. It will probably need to be some type of hell bent volcanic world, but I do not know what that would look like from orbit. Any suggestions?

Finally I have not been able to inject any random objects into gravity because I don?€™t know how and can not find any options in version 2 of gravity nor is it in the online FAQ. I?€™m fairly sure that the asteroid belts that I outlined will work.

Here is the new and improved Vilox.



You can download and play with the textures here 2.1MB.

Also if anyone is willing to help me with making better textures I would appreciate it. Right now Vilox is using its original texture, however because I have changed the class of planet from Mercurian to somewhere between a Ferrinian (High Metal content) world and a Volcanic world, I need to update the textures. I still want the planet to be heavily cratered but I need to add the element of high volcanic activity. I add a night texture to illustrate that the planet is highly active, but I think I over did it.

Right now I am using 1k textures for easy distribution but I would rather up that to 2k or 4k textures and increase the quality.

Update: I upgraded the textures to 4K and add a better night side map for the tectonic activity.

You can download and play with the 4k textures here 12.6MB.

One question; what are the oval shaped regions of coloured space surrounding Vilox in that image?

[MKruer]

That would be the ionized partials from the solar winds bouncing off the magnetosphere. In theory if the plant has a strong enough magnetic field and is close enough to the star, the amount of deflection should be visible in the visible light spectrum if you could remove the solar glare.

Sorry,but the Rylix system don??t work in my system.I unzip to Celestia 1.3.2 extras and even put 999999:Rylix in the starnames.dat,but Celestia didn??t recognize it.I type Rylix and the name is not show in the top of the screen.I don??t know what is happening...
The system is there,but I can??t go to it.

hum.. The system was designed with 1.4.0, and I don?€™t remember if Celesita 1.3.2 supports the extras directory. You could move the files and the related images into the data directory. That how it worked in 1.3.2 I believe, but it?€™s just been too long to remember.

[eburacum45]

You should create an .stc file for the star, and place it in the extras directory with your planets. I have made quite a few .stc files in the past; they are quite easy (as long as you remember to convert right ascension into degrees).

Going back to the magnetosphere- that is interesting. How did you get the effect?

[MKruer]

Thats funny the stc for the star is in the all the zip files.

Vilox is really three planets in one plus a comet. The first being Vilox which is like a normal planet, and then there is Vilox Inner Bow Wave and Vilox Outer Bow Wave and Vilox Atmosphere Evaporation Tail (the comet part). Then what I did was I took both bow wave planets, tilted them 90 degrees, and gave them a precession rate equal to the orbital period. Next I gave the two planets a negative Oblateness to create the egg shape look. Then I create an atmosphere on the egg shape planet and the cloud layer a height several thousand km above the planet surface. Finaly I add a semi transparent cloud image. That reminds me, does anyone know of a way to add an object to a system but not have it show up in the solar system browser. I would like to hide the listing of the extra parts of the planet.

PS. I love the Orion?€™s arm project.

The zip file went with the stc file.Unfourtanetely,it didn??t work.I am going to give up...

Matt. That's looking good. Where are the roid belts?

In the solar system, the main asteroid belt is between Mars and Jupiter, and it is believed to be a planet that tried to form there but couldn't. I would suggest to emulate the solar system and have two of your asteroid belts flanking the big fat cat; one on the inside, one outside; like at 4 and 11 au's.

I added the content of the stc file to the first post of this thread, and I think I figured out the problem. For version 1.3.2 did you add Rylix system under the data directory or the extra directory. If it?€™s in the data directory all the files need to be in the root. It will not work if you are placing them in the data/rylix folder. See if that works.

The asteroid belts will be the last thing I do, manly because they are huge, with potential hundreds of thousand of object per belt, but also because it can be generated via script and most of the objects are uninteresting. If there is a particular object in the belt, I will add it to the default set of planets. Also to ease

Also to ease your concern I have two massive planets that form the belts. The first one is Gigus, this one object alone could generate the main belt as well as the minor belt between Hyperion and Praelos. Praelos over time has cleared its own path and clean out its local space. And even if a asteroid strike on the planet was 1000 times more likely then it would be on earth you are still talking about a major E.L.E once every what , 100,000 to million years? This would be a good reason why no intelligent life ever evolved on the planet and would explain why there are not many ?€?creatures?€
