How about a little lore to spice the world up? Pictured above is Carthage-2, one of the biggest industrial strongholds in Solarian space, famed for the massive shipyards and abundant resources to be mined and refined there.
Located in Vega, it is of course also a key planet of major strategic importance in the Sol-Gliese War. As such, the lower orbital zone is formidably well defended by sensor posts within the ring along with massive sentry networks.
On it's fairly temperate surface, around 2.4 billion people reside in the cities all over the planet. While industry and manufacturing are the largest economic sector here, there has been a decent increase in tourism recently as well, from people in other systems coming to observe the rings or watch new ships get constructed in their harbours.
Colonization began way back in 2189, being one of the first successful colony projects, as a joint effort within the USDF (back then still being known as the Greater Earth Union).
