What is the Great Square of Pegasus?

The Great Square of Pegasus is a prominent asterism – a visually recognizable pattern of stars – located in the constellation Pegasus. It’s not a constellation itself, but rather a key part of Pegasus, easily identifiable in the autumn skies. On september 3rd, 2025, it offers a fantastic viewing opportunity for both seasoned stargazers and beginners. This large, almost perfectly square formation is formed by the stars Alpheratz, Scheat, Markab, and Sirrah.Understanding its location and the stars that comprise it is key to enjoying this celestial spectacle.

Locating Pegasus in the Night Sky

Finding Pegasus and its Great Square is relatively straightforward. Here’s a step-by-step guide:

1. Look East: In early September, Pegasus rises in the eastern sky after sunset.
2. Identify Andromeda: First, locate the constellation Andromeda. It’s recognizable by its “V” shape.
3. Follow the Chain: Pegasus is directly adjacent to Andromeda. Imagine a chain connecting Andromeda to the Great Square.
4. The Square’s Orientation: The Great Square appears to be tilted, resembling a diamond more than a perfect square. This is due to Earth’s perspective.
5. Use Star Charts & apps: Utilize stargazing apps like SkyView Lite, Star Walk, or Stellarium to pinpoint Pegasus’s location based on your specific time and location. these apps are invaluable tools for night sky observation.

The Stars That Form the Square

Each star within the Great Square has its own unique characteristics:

Alpheratz (Alpha Andromedae): Technically located in Andromeda, Alpheratz is often considered part of Pegasus, forming one corner of the Square. It’s a shining, blue-white star.

Scheat (Beta Pegasi): A yellow-orange giant star, Scheat marks another corner of the Square.

Markab (Gamma Pegasi): A white star, Markab completes one side of the Square.

Sirrah (Delta Pegasi): Also known as Al-Sirrah, this blue-white star forms the final corner of the Great Square.

These bright stars make Pegasus easily visible even in areas with moderate light pollution.

Observing Tips for September 3rd, 2025

To maximize your viewing experience on September 3rd:

Dark Location: Escape city lights. The darker your observing site, the more stars you’ll see.

Binoculars or Telescope: While the Great Square is visible to the naked eye, binoculars or a telescope will reveal fainter stars and deep-sky objects.

Red Light: Use a red flashlight to preserve your night vision. White light will ruin your dark adaptation.

Dress Warmly: Even in early September, nights can get chilly.

Patience: Allow your eyes at least 20-30 minutes to adjust to the darkness.

Check the Moon phase: A bright moon can wash out fainter stars. Ideally, observe during a new moon phase. Moonless nights are best for stargazing.
