Mola:

  • Orbital Distance:  0.3 AU
  • Orbital Period:  0.1 Earth-years
  • Keplerian Ratio:  2.7
  • Radius:  7,608 km
  • Day Length:  18.4 Earth-hours
  • Atmospheric Pressure:  3.78 atm
  • Surface Temp:  625 °C
  • Surface Gravity:  0.82 g
  • Mass:  1.158 Earth-masses

For a terrestrial planet, Mola hurtles around the system’s star at breakneck speed. Its rapid orbit and molten core cause oceans of magma to be pumped out onto the surface, cooling into the continent-sized formations then erased by fresh flows of molten rock.

Atos:

  • Orbital Distance:  1.0 AU
  • Orbital Period:  1.0 Earth-years
  • Keplerian Ratio:  1
  • Radius:  7,556 km
  • Day Length:  40.4 Earth-hours
  • Atmospheric Pressure:  _ 0.44 atm
  • Surface Temp:  _ 1,157 °C
  • Surface Gravity:  _ 0.66 g
  • Mass:  _ 0.78 Earth-masses

Atos Irn was claimed, along with the rest of its system, after the volus learned FTL travel. In the great volus exploration push of 300 BCE, the species found only a few planets capable of supporting their colonies. They did, however, discover many planets teeming with valuable elements.

The orbiting robo-mining platforms of Atos Irn have since been shot through by the Reapers. Little remains except the occasional bit of space debris posing a navigation hazard.

Yan Tao:

  • Orbital Distance:  1.6 AU
  • Orbital Period:  2.0 Earth-years
  • Keplerian Ratio:  1.024
  • Radius:  11,460 km
  • Day Length:  37.9 Earth-hours
  • Atmospheric Pressure:  133.1 atm
  • Surface Temp:  325 °C
  • Surface Gravity:  1.45 g
  • Mass:  4.647 Earth-masses

Even by volus standards, the pressure on Yan Tao is crushing. With an atmosphere composed of carbon dioxide, argon, and small traces of oxygen, the surface is devoid of life. However, tiny, fossilized sea creatures have been discovered in the deepest crevices of what used to be Yan Tao’s oceans.

Kailo:

  • Orbital Distance:  3.2 AU
  • Orbital Period:  5.7 Earth-years
  • Keplerian Ratio:  1.009
  • Radius:  11,489 km
  • Day Length:  93.9 Earth-hours
  • Atmospheric Pressure:  (trace) atm
  • Surface Temp:  -93 °C
  • Surface Gravity:  0.91 g
  • Mass:  2.931 Earth-masses

Kailo‘s frigid surface is dotted with impact craters left during a legendary meteor shower that happened more than 400,000 years ago. The meteors contained traces of cobalt, but not enough to warrant a full-scale mining expedition. The volus have largely left Kailo alone, as have the Reapers.

Solu Paolis:

  • Orbital Distance:  6.6 AU
  • Orbital Period:  17.2 Earth-years
  • Keplerian Ratio:  0.972
  • Radius:  28,567 km
  • Day Length:  14.7 Earth-hours
  • Atmospheric Pressure:  _ atm
  • Surface Temp:  _ °C
  • Surface Gravity:  _ g
  • Mass:  _ Earth-masses

Solu Paolis‘s helium-3 collection mechanisms historically turned a large profit, not because of any great immigration into the Esori system, but because Solu Paolis made a good refueling stop between Irune and Satu Arrd.

Warned of the Reapers‘ battle plans but left with little other option, a select team of workers at Solu Paolis sent out phony communications suggesting that important military data was being handed off here. When the Reapers sent in a force of husks, they ran into the volus‘s trap: a chain reaction that annihilated the station.
