Erros:

Orbital Distance: 0.8 AU
Orbital Period: 0.7 Earth-years
Keplerian Ratio: 1.045
Radius: 7,095 km
Day Length: 37.6 Earth-hours
Atmospheric Pressure: Trace atm
Surface Temp: 127 °C
Surface Gravity: 1.33 g
Mass: 1.634 Earth-masses

Erros is a turian word meaning “overlook” or “pleasant view,” not to be confused with humanity’s mythological Eros. The name refers to the planet’s nearly absent atmosphere, allowing visiting probes and rovers a sweeping view of its volcanic mountains. Erros’s hematite deposits give the world a reddish color. Accessible deposits of iron and copper have attracted second-tier turian and volus conglomerates that robo-mine the surface.

Gellix:

Orbital Distance: 1.6 AU
Orbital Period: 2.0 Earth-years
Keplerian Ratio: 1.024
Radius: 3,842 km
Day Length: 19.4 Earth-hours
Atmospheric Pressure: 0.40 atm
Surface Temp: 4 °C
Surface Gravity: 0.774 g
Mass: 0.279 Earth-masses
Colony: Turian
Capital: Anapondus, founded 658 CE (krogan), 801 CE (turian), population 54,000

Gellix was given to the krogran [sic] after the Rachni Wars, but bitterly contested in the Krogan Rebellions and reconquered by the turians. This left the turians as caretakers to a levo-amino-acid-based world that they could not inhabit themselves but were unwilling to give up.

In cooperation with the Vol Protectorate, the turians attempted to rent the planet out for colonization. Between the high price and a surface littered with unexploded ordnance, however, Gellix found few reputable tenants. Its most notable inhabitants were penal colonies. To those who know of it today, Gellix is a symbol of tragic waste–an entire garden world nearly forgotten by the galaxy at large.

Antinax:

Orbital Distance: 3.05 AU
Orbital Period: 5.3 Earth-years
Keplerian Ratio: 1.01
Radius: 9,584 km
Day Length: 34.2 Earth-hours
Atmospheric Pressure: 20.88 atm
Surface Temp: 214 °C
Surface Gravity: 1.5 g
Mass: 3.362 Earth-masses

A large terrestrial planet, Antinax has been passed over by the turians and potential investors alike. When the turians won the planet from the krogan, they sought to sell mineral rights, but ultimately found no buyers. One survey team dubbed it “a stinking world with nothing to recommend it but brimstone and bad steel,” and, like Gellix, the planet was soon forgotten.

Despite being farther from its parent star than Gellix, Antinax has a thick atmosphere of nitrogen, methane, and ethane–greenhouse gases that retain significant heat. There are four valuable minerals on Antinax, the most abundant being sulfur and iron.

Nirrus:

Orbital Distance: 6.2 AU
Orbital Period: 15.5 Earth-years
Keplerian Ratio: 0.992
Radius: 56,378 km
Day Length: 12.6 Earth-hours
Atmospheric Pressure: N/A atm
Surface Temp: N/A °C
Surface Gravity: N/A g
Mass: N/A Earth-masses

Nirrus, a moderate-sized hydrogen-helium gas giant, is of mild interest to turian scientists because of its abnormal atmospheric composition. The planet has only a fraction of the expected methane, with high levels of carbon monoxide and ethylene instead.
