Delta Pavonis
Factual
(NB: There is some disagreeement in the published data about this star, as noted in square brackets below.)
A yellow-orange dwarf star (type G5-8 V-IV) [Wikipedia says G8-IV] about 19.9 light years from our sun, Sol. Very slightly larger [1.22 Rsol, Wiki], heavier [but Wiki says 0.991 Msol] and brighter [1.22x Sol] than Sol. A planet in its habitable zone would be slightly further from it than Earth is from the Sun, and its year would be about a month longer than Earth's (410 days). Figures for its metallicity range from 0.95 to 2.7 times as enriched as Sol [Wiki 2.14x for Fe], and while its age is unknown [Wiki 6.6 to 6.9 GY], it could be as much as 2 billion years older than our sun.
Temp of atmosphere: 5604K (vs 5780 for Sol)
Luminosity: 1.22 Sol (or 1.26?)
Abs Magnitude: 4.62
We assume a luminosity of 1.22 and, based on this, a mass of 1.0685.
Fictional
The planet Delta Pavonis III, or Verdigris, is habitable and hosts at least two human settlements, Verdigris City and New Toronto. It was home to a now-extinct neolithic-level intelligent species. (See Verdigris for additional detail.)
The system has at least one gas giant (Zeus) with an Enceladus-like ice moon, which can be used for refueling instead of landing on Verdigris.
