Top 5 Constellations to See in Autumn 2025

Autumn - or fall, as it's often called - may not get as much attention as summer for stargazing, but in many ways, it's the perfect season. The nights arrive earlier, the air turns crisp and clear, and the bugs of summer are finally gone. As the Milky Way arches across the sky, a whole new cast of autumn constellations takes center stage.

Some are bright and easy to spot, others reward you with hidden treasures if you know where to look. Whether you're heading out with just your eyes, a pair of binoculars, or a small telescope, fall offers plenty of cosmic landmarks worth discovering.

1. Pegasus - The Winged Horse

Pegasus is one of autumn's great guides. Imagine a giant square of stars rising in the east after sunset - that's the famous Great Square of Pegasus, and it's hard to miss once you know where to look.

Ancient skywatchers saw the outline of a flying horse here, but today most stargazers know it as a gateway. Once you've found Pegasus, you've unlocked the map to several other constellations and even one of the most famous galaxies in the sky.

• What to look for: Pegasus is famous for the Great Square of Pegasus, an easy-to-spot asterism made of four bright stars.
• Why it's special: The square is like a signpost - once you find it, you can use it to locate other constellations and even the Andromeda Galaxy nearby.
• Best viewing: High in the eastern sky during autumn evenings.

2. Andromeda - The Chained Princess

Stretching gracefully from Pegasus is Andromeda, a constellation steeped in myth but beloved by modern skywatchers for a different reason: it holds our nearest galactic neighbor.

With a dark sky and no telescope at all, you can actually see the faint smudge of the Andromeda Galaxy with your own eyes.

Few experiences in amateur astronomy compare to realizing you're looking at light that has traveled over two million years just to reach you.

• What to look for: Andromeda stretches out from one corner of Pegasus' square.
• Why it's special: Inside Andromeda lies the Andromeda Galaxy (M31) - the closest major galaxy to the Milky Way and visible with the naked eye from dark locations.
• Best viewing: East of Pegasus, on clear, moonless nights.

3. Cassiopeia - The Queen's Throne

If Pegasus is autumn's signpost, Cassiopeia is its crown jewel. Easily recognized by its bold W-shape of stars, this constellation dominates the northern sky in fall.

Ancient cultures imagined a vain queen perched on her throne, but today Cassiopeia is more like a cosmic compass. Once you've spotted that distinctive W, you can navigate to the North Star or use it to hop your way across some of the most rewarding patches of the night sky.

• What to look for: Cassiopeia's five bright stars form a distinctive W-shape.
• Why it's special: This constellation is a great guide to the north - opposite Cassiopeia lies the Big Dipper, with Polaris (the North Star) in between.
• Best viewing: Almost circumpolar from mid-northern latitudes, meaning you can see it all night long in autumn.

4. Perseus - The Hero

Perseus rides into the autumn sky alongside Andromeda and Cassiopeia, carrying with him both myth and spectacle. The constellation is home to a dazzling double cluster of stars - two swarms of suns so close together that they spill into each other in binoculars.

It's also tied to one of the year's most famous meteor showers, the Perseids, which seem to spring from this heroic figure each August. Even after the meteor show fades, Perseus remains a rewarding target through the fall.

• What to look for: A starry arc stretching out from Andromeda and Cassiopeia.
• Why it's special: Perseus is home to the famous Perseus Double Cluster - two star clusters side by side, stunning through binoculars. It's also the radiant point of the Perseid meteor shower (though that peaks in August, it's still a must-know constellation).
• Best viewing: Rising in the northeast on autumn evenings.

5. Aquarius - The Water Bearer

Aquarius doesn't shine as brightly as some of its autumn companions, but that's part of its charm. Stretching quietly across the southern sky, it's a sprawling constellation with deep roots in ancient sky lore.

To the Babylonians, it was the "Great One," pouring life-giving waters over the Earth. Today, it still pours surprises for patient observers: planetary nebulae, faint galaxies, and other treasures that binoculars and telescopes reveal.

For those willing to search a little harder, Aquarius offers a rewarding dive into the fainter side of the night sky.

• What to look for: Aquarius can be tricky because its stars are fainter, but look south for a sprawling constellation shaped like streams of water.
• Why it's special: In mythology, Aquarius is one of the oldest constellations. In astronomy, it's home to several planetary nebulae, like the Helix Nebula.
• Best viewing: Best seen in darker skies, away from city lights.

Tips for Spotting Autumn Constellations

• Use a star map or app - apps like Stellarium or SkySafari make it easy to locate constellations.
• Pick a dark spot - autumn nights are long, so travel away from city lights if you can.
• Binocular bonus - a simple pair of binoculars will reveal galaxies, clusters, and nebulae hidden in these constellations.
