Phi2 Pavonis
star in the constellation Pavo
Phi2 Pavonis (φ2 Pav, φ2 Pavonis) is a solitary star in the southern constellation of Pavo (the Peacock). It is faintly visible to the naked eye with an apparent visual magnitude of +5.10. Based upon an annual parallax shift of 40.55 mas as seen from Earth, it is located 80.4 light years from the Sun. At that distance, the visual magnitude is diminished by an extinction factor of 0.07 due to interstellar dust. It is a member of the thin disk population.
This is a yellow-white hued G-type main sequence star with a stellar classification of G0 V Fe-0.8 CH-0.5. This notation indicates the surface abundance of iron and cyanogen are below normal for this class of star. It is around 5.7 billion years old and is spinning with a period of around 28 days. It has an estimated 1.09 times the mass of the Sun and is 1.86 times the Sun's radius. The star is radiating 3.39 times the solar luminosity from its photosphere at an effective temperature of 6,091 K.
This system was in 1991 a test case for the Zeta Herculis moving group, of low metallicity stars with 5 billion years of age.

Why this record matters
“Phi2 Pavonis” is worth following because a concise public description often conceals a longer documentary argument. Here, Phi2, Pavonis and star provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 11, 2026. The linked authority identifier is Q979334. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1991.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
