Empyria

Empyria is a planetary system orbiting a yellow G-class star.  The system lies in the Perseus Constellation of the Mirfak Region.

 
The primary planet of the Empyria system is a small terrestrial world with a thick atmosphere.  The thick atmosphere creates crushing pressure on the surface, making it impossible for any permanent settlements to be built on the surface.

Massive arcologies were built towering above the surface, aided by the planet's low gravity, the arcologies rise high into the atmosphere where conditions are more earth-like.  The arcologies house millions in tall tower-like structures in the planet's upper clouds.

Empyria is one of the most unique and beautiful worlds with its people living in the clouds.  The people of Empyria are often considered wealthier than many other worlds in the region.  The primary planet houses nearly the entire population of the system.  Much of the rest of the system is rich in valuable resources and has been heavily mined over the years.

Empyria B
Empyria B is a hot dry world similar to most terrestrial worlds close to the parent star.  The world does have a few small mining colonies which operate during the long 40 day nights on the planet.  Much of the planet is rich in titanium meaning that mining is very profitable.

Distance: 0.71 AU

Orbit: 229 days

Temp: 312 K

Mass: 0.25 Earth

Radius: 4250 km

Gravity: 0.56 g

Rotation: 82 days

Moon(s): 0

Empyria C
Empyria C is a small terrestrial world with a cloudy, thick atmosphere.  Pressure at the surface is much too high, for that reason it was believed that the planet was uncolinizable despite having a relatively earth-like atmospheric composition .  A solution was found, on the surface towering arcologies were built that rise above the clouds, where the atmosphere is thinner and more earthlike.

Distance: 1.1 AU

Orbit: 441 days

Temp: 291 K

Mass: 0.21 Earth

Radius: 3712 km

Gravity: 0.63 g

Rotation: 29 hours

Moon(s): 3

Empyria D
Empyria D is an icy world with similar temperature to Mars in the Sol System.  The planet is often times considered a good candidate for terraforming, expect it is fairly dry and large amounts of water would have to be brought in from elsewhere (most likely comets).  The planet has a thin atmosphere of carbon dioxide.

Distance: 1.59 AU

Orbit: 764 days

Temp: 205 K

Mass: 0.76 Earth

Radius: 5965 km

Gravity: 0.87 g

Rotation: 46 hours

Moon(s): 1

Empyria E
Empyria E is small terrestrial world.  The planet contains large amounts of sulfur on the surface and in the thin atmosphere left over from a recent highly volcanic period.  The sulfur acts as a greenhouse gas keeping the planet warmer than it would normally be.  The planet is used primarily as a base for mining colonies established in the nearby asteroid belt.

Distance: 2.4 AU

Orbit: 3.9 years

Temp: 170 K

Mass: 0.09 Earth

Radius: 3065 km

Gravity: 0.37 g

Rotation: 23 hours

Moon(s): 1

Empyria F
Empyria F is a stormy, windy, hydrogen helium gas giant.  The planet is the largest body in the solar system.  A substantial amount of helium-3 exists deep below the clouds but is difficult to mine.

Distance: 8.67 AU

Orbit: 26.6 years

Temp: 82 K

Mass: 1.26 Jupiter

Radius: 75435 km

Gravity: 2.86 g

Rotation: 12 hours

Moon(s): 9
