| dbo:abstract | φ Pegasi, Latinised as Phi Pegasi, is a solitary, reddish hued star in the northern constellation of Pegasus. With an apparent visual magnitude of around 5.1, it is a faint star that can be seen with the naked eye. Based upon an annual parallax shift of 7.05 mas as seen from Earth, the system is located around 460 light years distant from the Sun. At that distance, the visual magnitude of the star is diminished by an extinction factor of 0.15 due to interstellar dust. This is an evolved red giant star with a stellar classification of M2.5 IIIb. It is a semiregular variable that ranges between magnitudes 5.11 and 5.17. Hipparcos mission photometry gives an amplitude variation of 0.0148 in magnitude with a frequency of 11.4 cycles per day. It is likely to be a semiregular variable and is tentatively classified as type SRb. In terms of its right ascension coordinates, φ Pegasi is located very near the line of the vernal equinox and will cross over around the year 3030, due to the precession of the Earth's axis.

(pt) Fi Pegasi (φ Pegasi, förkortat Phi Peg, φ Peg), som är stjärnans Bayer-beteckning, är en ensam stjärna i den östra delen av stjärnbilden Pegasus. Den har en genomsnittlig skenbar magnitud på +5,107 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätningar i Hipparcos-uppdraget på ca 7,1 mas beräknas den befinna sig på ca 460 ljusårs (142 parsek) avstånd från solen. På det beräknade avståndet minskar stjärnans skenbara magnitud genom en skymningsfaktor med 0,15 enheter på grund av interstellärt stoft.
