Vega

Vega is a planetary system orbiting a blue/white A-class star.  The system lies in the Lyra Constellation of the Inner/Sol Region.

 
Located only 25 light years, Vega was one of the first systems explored by the Terrans. Plans were devised to mine the system's mineral rich terrestrial worlds, then export their resources back to Earth. They would use the resources to help build needed space infrastructure across the Inner Region

Decades were spent to eventually build small colonies on the system's two terrestrial worlds. Numerous complications with the intense radiation from Vega delayed the planets' colonization projects.

Enclosed cities were eventually built around the warmer Vega B polar regions, also around the equator on cooler Vega C. An intricate system of high speed railway lines were constructed, they connected the mines to the enclosed cities.

Vega B
Vega B is a warm terrestrial world orbiting on the inner edge of Vega's habitable zone. Vega B has a thick atmosphere of Nitrogen and Helium, it's surface is composed of various volcanic rocks. Though the majority of Vega B is cool enough for liquid water, it is still very dry and intensely hot for humans. The most habitable areas are near the poles were the enclosed cites were built.

Vega C
Vega C is cooler than the inner Vega B, orbiting on the outer edge of Vega's habitable zone. Vega C has a carbon dioxide atmosphere. Though much of Vega C is frozen, parts of the planet can warm up during the summer to comfortable temperatures.
