Here's the Gliese 581 System, based on how not only I think about the way the planets look, but also based on the aspects of the program.
There are 5 planets, 3 are known to exist, e, b and c, and the other 2 are unconfirmed planets, g and d.
So (Unconfirmed) is put at the end of the names of those 2 planets, since we don't know if they really exist, though new analysis suggested they they may exist after all.
Here's the sim for those of you who don't feel like making it.
