Nice system, I think it would be better if you gave the planets names instead of just numbers, and made some of them orbit closer to the star, but nice system.
Here's my Pola system with:
Kronaxo, a very warm planet which is a little bit like Mercury (but purple/brown).
Zivo, which is a little bit like Earth.
Noxium, which was earlier called Noxunoy, a colder planet than Earth, where water can only exist near equator. It has some special purple forests north of the green belt in the middle, which makes much of the planet purple. It's perfectly orbiting Pola without any axis--- err... 0 degrees. So it's very dark in the polar areas. Noxium is the home planet of a space empire.
Klanaxon, a huge red gas giant, much bigger than Jupiter.
And
Uxnua, which is a dark green-blue planet where some strange parrot-like creatures live... Uxnua is a gas giant, and don't ask me how parrots can live on gas giants, they just can, ok?!
I might add more planets later... Hope you like the system. I'm also going to add Noxium's moon called Voltex.
Btw very nice program, Dan! Now I feel sorry for only paying 10... Perhaps I can pay some more one day or something, because this program is worth more than 10$.
