I like the co-creation theory where the earth when formed itself had a disc of dust from it's gravity in the early solar system and that ring of dust then coalesced into the moon.

Earth - Theia

I do not know if Theia could have met Venus, but if the Earth had captured Theia, we might have something like this here.

Well personally I think life would have evolved though, there was probably single celled life or microbes before Theia hit.


Correct. There have been several studies on the subject of Earth sized/Earth Mass planets without large moons and they've concluded that a large moon is not required for life to start or evolve.

http://www.astrobio.net/news-exclusive/ ... ical-life/

Thinking that Earths were rare in the galaxy was a pillar of the Rare Earth Hypothesis which Kepler data has kind of torn asunder.  ie: You couldn't end up with a planet the size of Earth except through collision. Which turned out to be false as a number of Earth sized and super-Earth sized planets have been found with Kepler yet we've still not found one exomoon. (albeit exomoons the size of our moon would be near the Kepler detection limits).

With Earth sized planets accounting for around 22% of planets in the galaxy, either there are far more Theia type collision than we thought or as modelling shows, you don't need them to end up with Earth sized and larger rocky worlds.

That is not true.  Earth size does not mean Earth like.  The rare Earth hypothesis includes much more than just size or distance from star.  Earth has many variables that could be required for complex life.

Of course. And a large moon may no longer be one of them. 
Always remember, nature surprises. Earth may be but one example of many types of habitable, terrestrial worlds. It would not shock me if we detect biosignatures at least of simple life, from planets quite unlike earth.

JackDole,I tested some of these addons in 0.9.8.0, most of them work decently.  Your previous mods, such as the Dyson sphere and rings, tend to spawn inside the star and bug out.

I tested the Proxima ring and that one loads properly but the "EqAscendNode" is off by about 80 on each.

DoctorOfSpace,
I can not test this now, but try this ring.
In SE 0.980, the direction of the Precession is reversed, that is, plus becomes minus and vice versa.

But I do not know if this is all that needs to be changed.

It is not, but it is the most glaring visual issue.  Something was changed, a few of the adjustments I have done have also become broken, will take a lot of work to fix them all.

Regarding the Dyson sphere:

This should create such a bubble. (Hopefully)

The star is called "D'handa Lyonitas C"

Since the system is still in work, it only contains few objects.
(It's from my WoW system.)

To make it look reasonable, **Eclipse shadows** must be turned off in the graphics settings.

Pitch Black

My attempt to recreate the system from the film.

scr00086.jpg

In my version, the planets are not so close together as in the film.
If the planets were so close together, predators would presumably be not the biggest problem.
Therefore, the night does not last as long as in the film.

The parameters and the names of the suns and planets I invented myself.

I wanted a system that is not completely impossible from the outset; so unlikely it may be.
Whether I have succeeded, I can not judge, for that, I'm not enough astronomer and mathematician.

If our solar system were cubistic, where am I here?
