56 Pegasi is a binary star system in the northern constellation of Pegasus. It is visible to the naked eye with a combined apparent visual magnitude of 4.74. The system is approximately 590 light years away from the Sun based on parallax, but is drifting closer with a radial velocity of −28 km/s. It is listed as a member of the Wolf 630 moving group. 56 Pegasi, som är stjärnans Flamsteed-beteckning, är en dubbelstjärna belägen i den mellersta delen av stjärnbilden Pegasus. Den har en skenbar magnitud på ca 4,74 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 2 på ca 6,1 mas, beräknas den befinna sig på ett avstånd på ca 530 ljusår (ca 160 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radialhastighet av ca –28 km/s. Stjärnan är listad som medlem i rörelsegruppen Wolf 360. 飛馬座56，又名BD+24 4716，HD 218356、SAO 91019、HR 8796，是飛馬座的一颗恒星，视星等为4.76，位于銀經95.12，銀緯-31.71，其B1900.0坐标为赤經23h 2m 14.3s，赤緯+24° -31.71′ 42″。

dbo:abstract
56 Pegasi is a binary star system in the northern constellation of Pegasus. It is visible to the naked eye with a combined apparent visual magnitude of 4.74. The system is approximately 590 light years away from the Sun based on parallax, but is drifting closer with a radial velocity of −28 km/s. It is listed as a member of the Wolf 630 moving group. The variable radial velocity of this star was announced in 1911 by W. W. Campbell. It is a single-lined spectroscopic binary in an assumed circular orbit with a period of 111.1 days. The a sin i value for this system is 0.01511 ± 0.00040 AU (2.26 ± 0.06 Gm), where a is the semimajor axis and i is the (unknown) orbital inclination. This value provides a lower bound on the true semimajor axis, which in this case is their actual separation. The primary component is a peculiar bright giant with a stellar classification of K0.5 II: Ba1 CN-2 CH-0.5. This notation indicates it is a K-type giant with some uncertainty about the classification, along with an overabundance of barium and underabundances of the CN and CH radicals. It is an active star, roughly 100 million years old, with 5.4 times the Sun's mass. The star has expanded to 40 times the radius of the Sun and is radiating 680 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,416 K. The system displays an excess of ultraviolet radiation that must be coming from the secondary companion. Simon et al. (1982) classified this object as a subdwarf O star. Alternatively, it may be a white dwarf companion with an accretion disk. Several puzzling features in the evolutionary history of this pair may be explained if the primary is a fast rotator being seen nearly pole-on. The star may have been spun up during a mass transfer episode with the secondary. 飛馬座56，又名BD+24 4716，HD 218356、SAO 91019、HR 8796，是飛馬座的一颗恒星，视星等为4.76，位于銀經95.12，銀緯-31.71，其B1900.0坐标为赤經23h 2m 14.3s，赤緯+24° -31.71′ 42″。 56 Pegasi, som är stjärnans Flamsteed-beteckning, är en dubbelstjärna belägen i den mellersta delen av stjärnbilden Pegasus.
