Stellar Wonders: Notable Stars in the Pegasus Constellation
Immerse yourself in the celestial narrative that Pegasus mythology weaves across the cosmos. Anchoring this mythic tale in the night sky are the leading luminaries of the Pegasus constellation—each shining with their own story. At the heart of this constellation lies the illustrious Enif, complemented by the essential stars that form the iconic Great Square.
The Myth and Reality of Enif, Pegasus’ Brightest Star
Your gaze upon the night sky might first land on the radiant Enif, also known as Epsilon Pegasi, a name derived from ‘nose’ due to its position marking the muzzle of the mythical horse. This orange supergiant of spectacular brightness, with a magnitude of 2.399, heralds as the beacon of Pegasus, guiding you through the constellation’s vast expanse.
Algenib, Scheat, and Markab: Cornerstones of the Great Square
The Great Square of Pegasus is not only an asterism; it acts as a celestial compass comprised of Markab, Scheat, Algenib, and the star shared with Andromeda, Alpheratz. Each star is pivotal, not only bookmarking the corners of the Great Square but also embodying its own unique characteristics within the constellation’s mythos.
| Star Name | Designation | Color | Type | Magnitude |
|---|---|---|---|---|
| Enif | Epsilon Pegasi | Orange | Supergiant | 2.399 |
| Markab | Alpha Pegasi | Blue-white | B9 III giant star | 2.49 |
| Scheat | Beta Pegasi | Red | Semi-regular variable star | 2.42 – 2.8 |
| Algenib | Gamma Pegasi | Blue | Beta Cephei variable star | 2.83 |
In the dance of these stellar giants, each contributes a verse to the Pegasus mythology—Enif (Epsilon Pegasi) as the narrator, Markab (Alpha Pegasi) with its steadfast glow, Scheat (Beta Pegasi) pulsing rhythmically in red hues, and Algenib (Gamma Pegasi) pulsating the heartbeat of Pegasus.
With the map of stars like Enif, Markab, Scheat, and Algenib before you, the Pegasus constellation becomes more than a myth—it’s a celestial journey studded with the depth of history and the brilliance of the night sky.

Exploring Deep Sky Objects within Pegasus’ Bounds
As you gaze upon the Pegasus constellation, you’re not only looking at an iconic group of stars but also a portal to an astonishing array of deep sky objects that whisper tales of the cosmos’s grandeur. Among these celestial wonders is Messier 15, also known as NGC 7078, a densely packed globular cluster that is one of the oldest known, with an age estimated at over 12 billion years. It’s a glittering testament to the early universe, located around 33,600 light-years away from Earth.
Another magnificent sight within the boundaries of Pegasus is the NGC 7331 galaxy. Often likened to our Milky Way, this spiral galaxy offers a stunning view of how our own cosmic home might appear from afar. Situated approximately 40 million light-years from our planet, NGC 7331 is a prime example of the universe’s elegant structure and symmetry.
In the company of galaxies, you’ll find Stephan’s Quintet, a visual grouping that stuns astronomers with its complex gravitational interactions. This compact galaxy group will have you marveling at how the force of gravity sculpted the universe into its current state. Nearby, the phenomenon known as the Einstein Cross showcases the astonishing effects of gravitational lensing wherein a single quasar appears quadrupled due to the bending of light around a massive galaxy.
Capping off Pegasus’s array of deep sky treasures is NGC 7742, also affectionately called the ‘Fried Egg Galaxy.’ This face-on unbarred spiral galaxy stands out with its bright core encircled by a ring of star formation, providing a literal window into the stellar life cycle.
