Known as the "Jackpot Solar System" to astronomers and scientists everywhere, this solar system consists of 2 sister planets, a medium sized gas giant, and a small rocky planet. What stands out is that one of the sister planets has a well developed habitable atmosphere as the other has a more dense atmosphere but is layered with metals to mine.
The rocky desert planet (as seen in the foreground) is known so far to contain large amounts of iron, gold, and nickel and there is a mining operation being planned to be built. Because of the dense atmosphere, breathing apparatuses are required by all personal while they are on the planet.
The tropical-like planet (seen in the background) was an astonishing find because the atmosphere resembles Earth's atmosphere very closely. Plans to colonize and terraform the planet are currently being planned.
So yeah, I was bored and wrote that whole backstory. Sorry if things might be off. The landscape was made in Terragen 2 (took 23 minutes to render; that was fun), put together in CS5, and images are from NASA [link]
I hope you enjoy.
