Within the constellation's borders there are 177 stars of apparent magnitude 6.5 or greater. [b] [10] Epsilon Pegasi, also known as Enif, marks the horse's muzzle. The brightest star in Pegasus, is an orange supergiant of spectral type K21b that is around 12 times as massive as the Sun and is around 690 light-years distant from Earth. [16]
ι Pegasi, Latinized as Iota Pegasi is a double-lined spectroscopic binary [8] star system located within the northern constellation of Pegasus, along a line between Lambda and Kappa Pegasi. It is visible to the naked eye as a yellow-hued point of light with a combined apparent visual magnitude of 3.77. [ 2 ]
This star has 2.09 [5] times the mass of the Sun and 2.6 [12] times the Sun's radius. It is radiating 25 times the luminosity of the Sun from its outer envelope at an effective temperature of 7,951 K. [12] The star appears to display a slight infrared excess. [13] θ Pegasi was suspected of being a binary star due to an acceleration detected by ...
1 Pegasi (1 Peg) is a triple star [10] system in the constellation Pegasus, located approximately 156 light years away from the Sun based on parallax. [1] It is visible to the naked eye as a faint, orange-hued star with an apparent visual magnitude of 4.09. [2] The system is moving closer to the Earth with a heliocentric radial velocity of − ...
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.
Gamma Pegasi is a star in the constellation of Pegasus, located at the southeast corner of the asterism known as the Great Square. It has the formal name Algenib / æ l ˈ dʒ iː n ɪ b /; [14] [15] the Bayer designation Gamma Pegasi is Latinized from γ Pegasi and abbreviated Gamma Peg or γ Peg.
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. It forms the upper right corner of the Great Square of Pegasus, [14] a prominent rectangular asterism.
ν Pegasi, Latinized as Nu Pegasi is a single [12] star in the northern constellation of Pegasus. It is an orange-hued star that is faintly visible to the naked eye with an apparent visual magnitude of 4.84. [2] The star is located approximately 261 light years away based on parallax, [7] but is drifting closer with a radial velocity of −19 ...
