Helios Gamma

Helios Gamma is a main sequence star of spectral class G9V and has a mass of 0.89. It was presumably the third system settled by the Colonials. It and Helios Delta orbit a common barycenter maintaining a separation of 70 SU. Helios Gamma is more massive and is closer to the system's barycenter. It completes an orbit once every 456 years.

• Planets and Other Astronomical Bodies
  • Thanatos - This planet, named after the god of death, has a corrosive 'sulphur' dioxide atmosphere and is tidally locked to its star.
  • Acheron asteroid belt - A broad asteroid belt, named after Sagittaron's largest river.
  • Libran - Features two small moons, Herse and Pandrossos, which are thought to be captured asteroids. The moons orbit so close to each other, they periodically swap positions.
  • Scorpia - Home to the Scorpion Fleet Shipyards. The planet features a half ring, thought to be a moon that broke apart nearly 100,000 years ago.
  • Sagittaron - A barren, mountainous world.
  • Ophion - A frigid gas giant with a diameter of 51,000 km, and an inclined orbit. The planet has 14 moons, all smaller than 10 km in diameter. Studies on the planet have Colonial scientists thinking that Ragnar was originally a member of the Helios Gamma system, while Ophion was not. Scientists think that Ophion was a rogue planet that passed close to Ragnar and was caught by the star, pushing Ragnar into its current orbit around the entire Gamma/Delta system.
