Ezka:

  • Orbital Distance:  1.2 AU
  • Orbital Period:  1 Earth-years
  • Keplerian Ratio:  1.728
  • Radius:  6,372 km
  • Day Length:  30 Earth-hours
  • Atmospheric Pressure:  78.43 atm
  • Surface Temp:  1,144 °C
  • Surface Gravity:  1.33 g
  • Mass:  1.318 Earth-masses

According to batarian propaganda, the batarian population exceeds the Council races, the batarian military is the most powerful, and the batarians’ unlivable hothouse planets are the hottest and most unlivable. Their best proof of this last point is Ezka, which closely orbits the scorching yellow-white star Untrel. Ezka’s nitrogen-heavy atmosphere might once have held oxygen, but if so, it burned off long ago. Even robo-miners don’t care for Ezka–although some modern mining equipment can withstand the heat, the machinery still gets stuck in the soup of molten light metals on the planet’s surface.

Reaper presence near Ezka seems light. Scans reveal wreckage orbiting the planet, likely destroyed Hegemony surveillance drones.

Klos:

  • Orbital Distance:  2.3 AU
  • Orbital Period:  2.7 Earth-years
  • Keplerian Ratio:  1.669
  • Radius:  10,116 km
  • Day Length:  64.3 Earth-hours
  • Atmospheric Pressure:  Trace atm
  • Surface Temp:  88 °C
  • Surface Gravity:  1.26 g
  • Mass:  3.146 Earth-masses

Klos is a rock planet with almost no atmosphere to speak of. Consequently, the planet retains fairly little heat considering how close it orbits to an energetic star. The relatively mild temperature made Klos attractive for robo-mining, with an emphasis on platinum. The planet also has an abundance of sodium oxide, used in the manufacture of lye, but profit margins on that compound are thin by comparison.

The Reapers have destroyed the orbital stations surrounding Klos and cut the strands of the space elevators that earlier generations of batarians used to transport goods to orbit.

Adek:

  • Orbital Distance:  4.5 AU
  • Orbital Period:  7.3 Earth-years
  • Keplerian Ratio:  1.71
  • Radius:  5,075 km
  • Day Length:  58 Earth-hours
  • Atmospheric Pressure:  0.45 atm
  • Surface Temp:  60 °C
  • Surface Gravity:  .78 g
  • Mass:  0.49 Earth-masses
  • Colony:  Batarian, population >6,000,000 (pre-invasion; before The Reapers)

Adek is a brutally hot and wet garden world, covered with molds and lichen analogues. It has many viruses and bacteria lethal to batarian physiology. The Hegemony colonized Adek early in its expansion, but few of the colonists wanted to stay. The result was domination by a class of landed slave-owners. A small cadre of well-paid engineers and skilled laborers kept the planet’s mechs and infrastructure functioning.

Alliance estimates put the planet’s batarian population at just over six million, but that number has likely fallen since the Reapers arrived.

Uza:

  • Orbital Distance:  18 AU
  • Orbital Period:  58.7 Earth-years
  • Keplerian Ratio:  1.693
  • Radius:  37,445 km
  • Day Length:  14 Earth-hours
  • Atmospheric Pressure:  N/A atm
  • Surface Temp:  N/A °C
  • Surface Gravity:  N/A g
  • Mass:  N/A Earth-masses

Uza is a methane-rich gas giant. The wreckage around the helium-3 infrastructure is unusual–it looks as if fleeing batarians tried to sever the collection equipment and take it with them when they were attacked. No Reaper ships, functional or otherwise, are immediately detectable, suggesting that the batarians may have actually turned on each other.
