33 Pegasi is the Flamsteed designation for a visual binary star in the northern constellation of Pegasus. It has an apparent visual magnitude of 6.2, placing it near the limit of naked eye visibility. Measurements show an annual parallax shift of 0.0298125″, which is equivalent to a distance of 109 ly (33 pc) from the Sun. It is drifting further away with a radial velocity of 24 km/s.

  • 33 Pegasi, som är stjärnans Flamsteed-beteckning, är en dubbelstjärna belägen i den östra delen av stjärnbilden Pegasus. Den har en kombinerad skenbar magnitud på ca 6,20 och är mycket svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 29,7 mas, beräknas den befinna sig på ett avstånd på ca 110 ljusår (ca 30 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet av ca 24 km/s. (sv)

  • 33 Pegasi is the Flamsteed designation for a visual binary star in the northern constellation of Pegasus. It has an apparent visual magnitude of 6.2, placing it near the limit of naked eye visibility. Measurements show an annual parallax shift of 0.0298125″, which is equivalent to a distance of 109 ly (33 pc) from the Sun. It is drifting further away with a radial velocity of 24 km/s. The primary component of this system is a main sequence star with a visual magnitude of 6.4 and a stellar classification of F7 V. It is nearly as old as the Sun with an estimated age of 4.1 billion years, but has a lower abundance of elements other than hydrogen and helium. The star has 1.3 times the mass and radius of the Sun. The stellar atmosphere has an effective temperature of 6,169 K, giving it the yellow-white glow of an F-type star. A faint, magnitude 9.3 companion star is located at an angular separation of 0.420 arc seconds along a position angle of 0.0°. The pair have a projected separation of 15.6 AU with an orbital period of about 250 years. (en)
