History

  • unknown: Due to the extreme compatibility/similarity of Centauran and Human DNA, as well as being the closest star systems to each other, there is a strong hypothesis that Alpha Centauri Prime was settled by Humans before the planet's recorded history.[1]
  • 1860: The Plague Wars begin when one of two competing city-state alliances on Alpha Centauri Prime releases biological weapons on the other.[2]
The year is uncertain, but it "lasted over a decade"[3]
  • 1871: An Emergency Medical Council comprised of an international team of scientists and doctors develops an effective antiviral agent and vaccine for the plagues sweeping Alpha Centauri Prime.[3]
  • Prior to 2045: Earth-launched probes do a flyby scan of the system, sending back data supporting possible life.[1]
  • 12 May 2065: Earth explorer UNSS Icarus arrives in the system and begins a 13-month visit with the inhabitants.[5][1]
  • 2217: Tritanium-hulled ship construction, including that of the Ranger and Triumphant sub-classes, begins in the Procyon and Alpha Centauri systems.[9]
  • Prior to 2231: Star Fleet decides to provide five transportable drydocks to Alpha Centauri to begin immediate production on the Rochester class cruisers.[10]

Important Locations

Notes

  • Alpha Centauri AB V may have moons with small colonies.[2]
  • Alpha Centauri AB VI may have moons with small colonies.[2]
  • Alpha Centauri AB VIII may have moons with small colonies.[2]
  • Alpha Centauri AB IX may have moons with small colonies.[2]
  • Alpha Centauri AB X may have moons with small colonies.[2]
  • Note: the original coordinates for the center of the trinary system was 3, 3, -3, which put it 5.2 light-years distant from Sol, too far by real distances; it has now been reset at 2.4, 2.5, -2.6 (4.33 lys). Some SFC sources still need to be updated to reflect the change.
