Does Sol have a twin?

I don't have any record of the "complete" status, unfortunately. Otherwise I could. ;)

OK then :)

So these systems are fully discovered and contain no gas giants:

So, to answer the OP's question more thoroughly:
I'm just curious.... have there been any other systems found that are nearly identical (same number of bodies, same configuration of bodies, same star type, etc) to Sol?
The answer is "no". Sol's configuration is very, very difficult for the Stellar Forge to replicate, and no-one has found one yet. Or at least, "no one" that has reported it to either the forums or third-party exploration tools.

Part of the problem is the restriction the Forge has placed upon itself in terms of the size of systems it generates. In Sol, the two outermost gas giant planets are quite remote, in terms of the Stellar Forge's ability to generate planets that far out. Uranus is 9173 LS from Sol, and Neptune is 14894 Ls. It is rare for the Forge to place gas giants in stable near-circular orbits beyond 10,000 LS, or even 5000 Ls, around G-type stars. Gas giants need lots of orbital room to form, so the odds are stacked against 4 GGs in a G-type system.

Of course, as others have pointed out, that doesn;t mean there isn't one out there somewhere in the galaxy. 400 billion is an awful lot of dice rolls; even if the odds of a Sol-twin (or near-enough-to-a-Sol-twin-to-count) are a one in ten billion chance, that's still, statistically, 40 of them out there waiting to be found.
 
If a system generator is incapable of generating our own solar system even once in 400 billion attempts then I think that's a pretty huge design fail.
 
I guess the question is also this-- If StellarForge can generate it at least once, would we be able to find it within the next thousand years? :D
 
I've made a realistic planetary system generator myself (for a scifi setting) and I've made a million systems and it made 49275 G V solo systems on this run - I've found a few dozen or so of those that have planets in 9 orbits (with the 5th being an asteroid belt). I don't have a great way to search through them all right now, but I'm finding some at least. Not Sol-clones by any means, but similar at least.

Not that it'll mean much to anyone here but this is one of the closest I've found - a 6 billion year old solo G0 V star with 4 terrestrials, one asteroid belt, and then four gas giants (the "Jupiter" is nearly 5 MJ, the Saturn's actually about right and the outer two GGs are very close to Uranus and Neptune. Fourth terrestrial is the same size and density bracket as earth but with a somewhat more eccentric orbit, but it's habitable ( a bit colder than earth) with a thinner but breathable atmosphere. The terrestrial orbital distances are a bit off from the Sol system but it's not too shabby.

Just to show that with the right parameters and assumptions it's possible to come close at least :)
