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]
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 ...
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]

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.
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 − ...
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.
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 ]
