|The planets of Alpha Centauri A+B; Ixion, Nessus, Hippodamia, Pholus, Pirithous, Coronus, Eurytion, Caenus; and the moons Polypoetes and Mnesimache
Alpha Centauri A and B
|Alpha Centauri A+B, Rigil Kent, Toliman, Bungula, FK5 538, GC 19728, CCDM J14396-6050, YTS 1271, JD1
|Distance from Sol:
|4.395 light-years (epoch J2000) (note: this was the location of the system when colonised; proper motion has brought this star system closer to Sol)
|RA 14h39m35.88s, -60.50'7.4 (epoch J2000)
|Orbit of A and B around one another
|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.
|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-

|Nessus, an unaltered Venus-like world; the capital word of the Alpha Centauri System. Although it is inhospitable to humans, this planet with its carbon-rich atmosphere is within the habitable range of the Nauri clade of von Neumann replcators
Alpha Centauri A
|Alpha Centauri A
|(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)
|Nessus Planetary type (Nolwocs) Cytherean (venus-like)
Eurytion Planetary type Arean.
Moon of Eurytion Mnesimache.
Pholus Planetary type Arean.
|The twin stars Alpha Centauri A+B
Alpha Centauri B
|Alpha Centauri B
|0.869 x Sol
|Ixion Planetary type Hephaestian.
Pirithous Planetary type Arean.
Moon of Pirithous Polypoetes.
Caeneus Planetary type Hermian.
Hippodamia Planetary type Titanian.
Coronus Planetary type LithicGelidian
|Ixion, a tidally-locked hot Earth (Vesperian/Hephaestian) planet. With a temperature of 1300K the sunward side of this planet is inhosptable even to the Nauri, but the cold far side has limited reserves of volatiles and supports a small population
Culture and Politics
|Several ai generated symbols
|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 and Culture:
|Culture: Iterative replication
Language: 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 Technocalypse; 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 Terragen 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)
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: The stargate orbits between A+B and Proxima, at a distance of 800AU, connected to Aksijaha.
Beamrider Cycler Routes: - major Cycler routes are available to Proxima Centauri, Ying, and the red dwarf SIPS 1259-4336
