 There's something missing here…This page is missing critical information of some kind. It might need a location, or names of people involved, or something else. It might be outdated. It might be a Wikipedia or SolStation data dump with little or no relation – or, worse yet, with contradictions – to the situation in Fenspace. It might have inconsistencies. It might even be missing multiple details. You can help FenWiki by expanding this page. |

Pi(3) Orionis is a (possibly multiple) star system located about 26.2 light-years away from our Sun, Sol. It lies at the western edge of the constellation Orion, the Hunter. This star is a white-yellow main sequence dwarf star of spectral and luminosity type F6 V, with maybe 1.3 times Sol's mass, 1.3 times its diameter[1], and three times of its luminosity. It may be anywhere from 20 to 151 percent as enriched as Sol with elements heavier than hydrogen ("metallicity"), based on its abundance of iron[2].
Pi(3) Orionis A is a New Suspected Variable designated NSV 1731. Star A has a probable optical companion[3] and may have a spectroscopic companion that speckle interferometry has not been able to resolve[4].
The distance from star A where an Earth-type planet would be "comfortable" with liquid water is centered around 1.7 AU -- beyond the orbital distance of Mars in the Solar System. Astronomers are hoping to use NASA's Terrestrial Planet Finder (TPF) and the ESA's Darwin planned groups of observatories to search for a rocky inner planet in the so-called "habitable zone" (HZ) around Pi3 Orionis. As currently planned, the TPF will include two complementary observatory groups: a visible-light coronagraph to launch around 2014; and a "formation-flying" infrared interferometer to launch before 2020, while Darwin will launch a flotilla of three mid-infrared telescopes and a fourth communications hub beginning in 2015.
