Sirius A (before starlifting), and Sirius B a tiny white dwarf (right) This picture is highly foreshortened to show the two stars together; in fact they are separated by 19.8 astronomical units on average |
System | Names: Alpha Canis Majoris, 9 Canis Majoris, GJ 244, HD 48915, HIP 32349, HR 2491, Sirius Stars: 2 Sirius (Alpha Canis Majoris A) Sopdet (Alpha Canis Majoris B) Location: - Distance from Sol: 8.601 ly - Constellation: Canis Major A-B binary orbit Orbital characteristics: - Average separation: 19.767 AU - Period: 50.128 years - Eccentricity: 0.591 |
---|---|
Star A | Names: Alpha Canis Majoris A, GJ 244 A, Sirius (Sirius A) Physical characteristics: - Mass: 2.063 x Sol - Radius: 1.711 x Sol - Luminosity: 25.748 x Sol (bolometric) - Temperature: 9,940 Kelvin - Spectral type: A1V - Age: 242 million years Note: Gravitational influence from Sopdet was strong enough that no planet was able to form in close orbit around Sirius. - The Amat Belt: 0.2 - 0.3 AU; belt of vulcanoids heavily industrialized prior to its removal. |
Star B | Names: Alpha Canis Majoris B, GJ 244 B, Sirius B, Sopdet Physical characteristics: - Mass: 1.018 x Sol - Radius: 5,843.9 km - Luminosity: 0.025 x Sol (bolometric) - Temperature: 25,000 Kelvin - Spectral type: DA2. - Age: 228 million years |
Planetary System | The two circumbinary planets in the Sirius system are named after the first man and the first woman in space, respectively. 1. Gagarin: SulfanoNeptunian Semi-major axis = 131 AU, Orbital period = 854 years, Eccentricity = 0.14, Mass = 27.4 x Earth, Radius = 27,520 km (4.32 x Earth) 2. Tereshkova: MethanoNeptunian Semi-major axis = 206 AU, Orbital period = 1,684 years, Eccentricity = 0.08, Mass = 19.9 x Earth, Radius = 22,810 km (3.59 x Earth) - The Outer Belt: 210 - 600 AU |
Colonisation | Robot probe launched 329AT, arrived 415AT. The first colonists departed Solsys in 655AT in the Sopdet, a GAIA ark, and arrived 698AT |
