σ Pegasi, Latinised as Sigma Pegasi, is a binary star system in the northern constellation of Pegasus. With a combined apparent visual magnitude of 5.16, it is faintly visible to the naked eye. Based upon an annual parallax shift of 36.66 mas as seen from Earth, the system is located 89 light years distant from the Sun. It has a relatively high proper motion, advancing across the celestial sphere at the rate of 0.524 arcseconds per year.

  • Sigma Pegasi (σ Pegasi, förkortat Sigma Peg, σ Peg) som är stjärnans Bayerbeteckning, är en dubbelstjärna belägen i den södra delen av stjärnbilden Pegasus. Den har en skenbar magnitud på 5,16 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 36,7 mas, beräknas den befinna sig på ett avstånd på ca 89 ljusår (ca 27 parsek) från solen. Den har en relativt snabb rörelse genom rymden och förflyttar sig med en hastighet av 0,524 bågsekunder per år. (sv)
