Alpha Centauri A+B - Data Panel
Galactography System: Alpha Centauri A+B
Location: Inner Sphere Distance from Sol: 4.395 light-years Coordinates RA 14h39m35.88s, -60°50'7.4 epoch 2000ce (note: this was the location of the system when colonised; proper motion has brought this star system closer to Sol) Orbit of A +B around one another Period: 79.92 years Semimajor Axis: 23.60 A.U.s Eccentricity: 0.516 Periastron distance: 11.42 A.U.s Apastron distance: 35.78 A.U.s Note; from Caenus, a planet orbiting Alpha Centauri B, the A component never appears brighter than 1/500th as bright as the Sun as seen from Earth. Companion: Proxima Centauri; a red dwarf more than 17000 AU distant with an orbital period of half a million years, this star has an independent nearbaseline human colony of great antiquity- More Alpha Centauri A
Star: Alpha Centauri A Stellar Type: G2 V Luminosity: 1.567 x Sol Planets: (note; the worlds of Alpha Centauri A+B were named by the exploration team which mapped them in 206 a.t; they are named after famous Centaurs and Lapiths of ancient Greek legend) 1/ Nessus : Planetary type (Nolwocs) Cytherean (venus-like) Diameter 18446 km Orbital Radius 08.08 AU Orbital Period (year) 0.695 standard years Rotation period (day) 13.23 hours 2/ Eurytion Planetary type Arean Diameter 9285 km Orbital Radius 1.6 AU Orbital Period (year) 1.94 standard years Rotation period (day) 18.2 hours 2a/ Moon of Eurytion: Mnesimache Planetary type Selenean Diameter 3922 km Orbital Radius 250,000 km Orbital Period 23 standard days tidally locked 3/ Pholus Planetary type Arean Diameter 12060 km Orbital Radius 2.783AU Orbital Period (year) 4.45 standard years Rotation period (day) 17.18 hours Alpha Centauri B

Polity Name: Cenaurinume Coalition Symbol: Several ai generated symbols Affiliation: House Centauri Founded/Colonized: 283 a.t. Notes: The Naurinumes of House Centauri are independent Von Neumann replicators, unaligned with the Sephirotic empires, the Panvirtuality or the Diamond Network, but with generally good relations with all three. Psyche, Art, Culture Culture: Iterative replicationLanguage: Naurinume OS code, with innumerable subdialects developed by each subclade; also many nauri are proficient in Anglic, Academic Coronese and any other language which may be necessary. Territory and Population Population:Von Neumann Replicators 190 billion, mostly on Nessus, Pholus and Hippodamia; Human nearbaseline 2 Billion mostly on Caeneus Vec: 4 Billion mostly on Eurytion Territory: The Nari Empire developed in the Dark ages following the Nanoswarms; von neumann probes were sent from Alpha Centauri A+B to nearby red and brown dwarfs such as SIPS 1259-4336 and have since spread to the furthest limits of the Terragen Sphere Government and Administration Government Type Naurinumes regularly exchange data packets containing experiences and subjective opinions; government is achieved by consensus of shared opinion Foreign Policy: Neutral independent house with formal treaties with the Sephirotic empires. particularly the Solar Organisation and the Terran Federation; also affiliated with the Metasoft Version Tree and the Silicon Generation Economics, Local Infrastructure Currency: energy value exchange units Major Industries: asteroid mining, iterative self-modification, some tourism Angelnetting : in some orbitals and cities. Population centers: Nessus Complex A, Nessus Complex B, Nessus Complex D, Nessus Complex E (Nessus Complex C was lost in the Third Nauri Dispute, a fierce war in the 68th century); Hippodamia Complex A, Hippodamia Complex B, Meatwad city (Caenus) Travel Major Spaceports: Toliman One Spaceport Rigil Kent Stardocks Freedom of Movement :The Nearbaseline Human polity known as the Centauri Traders based on Caeneus have negotiated freedom of movement for human-derived species within the Centauri A+B system; however entry to Nessus is restricted Environmental Requirements :The Nauri have not terraformed any of the planets in this system, instead they have adapted themselves to the planets as they are; for this reason nearbaseline tourism is restricted to Caeneus unless heavy duty protective suits are worn, or the tourist submits to extensive modification. Virtual tours involving telepresence are available. Sites of Interest:The ancient landing sites of the first Von Neumann probes are preserved on every planet; venerable non-Nauri historical sites are also popular on Caenus and Eurytion. The grand Fabricator in Nessus Complex A is no longer used, but is an piece of interesting industrial archeology. Stargate - a single stargate orbits between A+B and Proxima, at a distance of 800AU. This stargate is connected to the Diamond Nexus, so is rarely used by citizens of the Sephirotic Empires, though Naurinumes use it frequently. Beamrider Cycler Routes - major Cycler routes are available to Proxima Centauri, Ying, and the red dwarf SIPS 1259-4336 |
History:
Alpha Centauri was colonised by Von Neumann Machines (neumanns) in the late Interplanetary Era; however these self-replicating machines were designed to be self-evolving and independent, and spontaneously rejected any further human contact once they arrived. This error in their programming led to the loss of the resource-rich Alpha Centauri system, the closest planetary system to Sol. Only in the Late Federation era were humans and human-derived clades allowed to enter the system; by this time the Naurinumes (as they became known) were as curious about humans as humans were about them.
However the Nauri mentality was entirely different to human psychology, and the Federation did not manage to persuade the Nauri consensus to become full members. Since that time the Naurinumes have remained independent, rarely becoming involved with the Sephirotic worlds.
Sometimes the replication imperative within the core program of the Nauri mentality becomes too strong, and a population of Naurinumes will start to expand exponentially somewhere on the Outer Periphery. Such rapid population growth is generally suppressed by one or another of the metaempires, often by invoking millenia-old agreements (individual Nauri exist for thousands of years, though they exchange personality elements on a routine basis). Sometimes the suppression is more problematic, and may involve force of arms.
