Yall-Ull System - Data Panel | |
System | Name: Yall-Ull, Gliese 667 (GJ 667), HD 156384, HIP 84709, HR 6426 Components: 3 1) Yelsal (Gliese 667 A) 2) Tehno (Gliese 667 B) 3) Arcas (Gliese 667 C) Location: - Distance from Guniibuu: 5.244 ly (J2000) - Distance from Sol: 23.873 ly (J2000) - Constellation: Scorpius |
---|---|
Yelsal | Name: Yelsal, Gliese 667 A Physical characteristics: - Mass: 1.452E+30 kg (0.73 x Sol) - Radius: 528,732 km (0.76 x Sol) - Luminosity: 0.254 x Sol (bolometric) - Temperature: 4,700 Kelvin - Spectral type: K3 V - Age: 8 billion years System: The two main dwarf planets that orbited around this star at 0.11 and 0.27 AU were restored to pristine conditions after the rise of the restorationist mindset in the system. Others were either taken apart for the construction of swarms of habitats and infrastructures that encircle this star, or rearranged into massive habitat complexes housing up to hundreds of billions of sophonts. |
Tehno | Name: Tehno, Gliese 667 B Physical characteristics: - Mass: 1.372E+30 kg (0.69 x Sol) - Radius: 486,990 km (0.70 x Sol) - Luminosity: 0.181 x Sol (bolometric) - Temperature: 4,500 Kelvin - Spectral type: K5 V - Age: 8 billion years System: Kbem, the most massive dwarf planet, orbiting this star at 0.30 AU, is the only major object in the Yall-Ull system that is completely covered in an ecumenopolis. Yelsal-Tehno binary orbit Orbital characteristics: - Average separation: 13.115 AU - Period: 39.86 years - Eccentricity: 0.58 |

Arcas | Name: Arcas, Gliese 667 C Physical characteristics: - Mass: 6.562E+29 kg (0.33 x Sol) - Radius: 222,624 km (0.32 x Sol) - Luminosity: 0.017 x Sol (bolometric) - Temperature: 3,700 Kelvin - Spectral type: M1.5 V - Rotation period: 105 days - Age: 8 billion years System: 1) L'daso: Acidi-Neptunian Cere-Jotunnian Semi-major axis = 0.049 AU, Orbital period = 7.200 days, Eccentricity = 0.13, Mass = 7.5 x Earth, Radius = 2.479 x Earth 2) Horvat: Hydro-Neptunian Cere-Jotunnian Semi-major axis = 0.121 AU, Orbital period = 28.16 days, Eccentricity = 0.03, Mass = 5.4 x Earth, Radius = 1.938 x Earth 3) Malkas: Tholi-Neptunian Cere-Jotunnian Semi-major axis = 0.265 AU, Orbital period = 91.40 days, Eccentricity = 0.08, Mass = 6.3 x Earth, Radius = 2.381 x Earth This planet is now covered by a habitable suprashell. Inner Yall-Ull - Arcas binary orbit Orbital characteristics: - Average separation: 220 AU - Period: 2,467 standard years |
