Proxima Centauri

✹ • ◦ ) ◦◦ ⦾....... )

Proxima Centauri is a red dwarf star with a contingent of five planets and an outer cometary disk. It is the closest star system to Sol, and while technically a gravitational subsystem of the Alpha Centauri binary, it is so distant that it is typically listed as a separate system. Proxima has no native life of its own; however, its two innermost worlds were partially hemeraformed millennia ago by the skgri.

Astrography

Location

Proxima Centauri lies in a very wide orbit around the Alpha Centauri binary system in a 550000-year cycle. It is currently just over 4 lightyears from Sol, placing it very close to the approximate center of known space.

Structure

Proxima Centauri is, as a component of the Alpha Centauri system, a solitary red dwarf star orbited by four planets and an outer debris disk. The two innermost planets are separate from the outer system by a large gap, filled by a scattered asteroid belt called the Proxima Belt.

Ecology

The Proxima Centauri system hosts two planets with introduced Hemeran ecologies: Prometheus and Menoetes. These worlds only have very simple macroscopic multicellular organisms atop their microbial ecosystems, indicating a mass extinction event in recent history or at the very least an incomplete mundiforming process.
