HR 8799 is a roughly 30 million-year-old main-sequence star located 133.3 light-years (40.9 parsecs) away from Earth in the constellation of Pegasus. It has roughly 1.5 times the Sun's mass and 4.9 times its luminosity. It is part of a system that also contains a debris disk and at least four massive planets.
51 Pegasi (abbreviated 51 Peg), formally named Helvetios / h ɛ l ˈ v iː ʃ i ə s /, [12] is a Sun-like star located 50.6 light-years (15.5 parsecs) from Earth in the constellation of Pegasus. It was the first main-sequence star found to have an exoplanet (designated 51 Pegasi b, officially named Dimidium) orbiting it. [13]
α Pegasi (Latinised to Alpha Pegasi) is the star's Bayer designation.It bore the traditional name Markab (or Marchab), which derived from an Arabic word مركب markab "the saddle of the horse", or is mistranscription of Mankib, which itself comes from an Arabic phrase منكب الفرس Mankib al-Faras "(the Star of) the Shoulder (of the Constellation) of the Horse" for Beta Pegasi.
Eta Pegasi or η Pegasi, formally named Matar / ˈ m eɪ t ɑːr /, [11] [12] is a binary star in the constellation of Pegasus. The apparent visual magnitude of this star is +2.95, [2] making it the fifth-brightest member of Pegasus. Based upon parallax measurements, the distance to this star is about 214 light-years (66 parsecs) from the Sun. [1]
Beta Pegasi (β Pegasi, abbreviated Beta Peg, β Peg), formally named Scheat / ˈ ʃ iː æ t /, [12] [13] is a red giant star and the second-brightest star (after Epsilon Pegasi) in the constellation of Pegasus.
