Orion’s Belt points to Sirius on September mornings

Sirius is the sky’s brightest star. You can always be sure you’re looking at the correct bright star by drawing a line from Orion’s Belt to Sirius. And from the Southern Hemisphere, turn the chart upside down.

Orion’s Belt points to Sirius

It’s one of the neatest tricks in all the heavens: Orion’s Belt points to Sirius, the sky’s brightest star.

On September mornings, you’ll find both Orion the Hunter and the very bright star Sirius in the eastern part of the sky before dawn. And before you know it, they’ll be shifting into the evening sky. So identify them now, and enjoy them for months to come.

Sometimes there are bright planets in the same region that might outshine even Sirius. For example, in September 2026, Jupiter is also in the morning sky and definitely outshines our brightest star. What’s more, bright planets often adorn the evening sky during the northern winter, when Orion and Sirius shine brightly. In these cases, how can you be sure the object you’re looking at is Sirius? The constellation Orion is your ticket. And no matter where you are, no matter what time of the year it is, Orion’s Belt always points to Sirius.

Orion returned to the morning sky in late July

Orion returned to the sky before dawn in late July and early August. Now in September, you can easily find this large constellation before sunup. Just look in the eastern part of the sky. You’ll easily notice Orion’s Belt, which consists of a short, straight row of three medium-bright stars.

And to find Sirius, draw a line through Orion’s Belt and extend that line toward the horizon. There, you’ll spot Sirius, the sky’s brightest star.

Sirius is in the constellation Canis Major the Greater Dog. Indeed, it’s often called the Dog Star.

And note bright Sirius is at the bottom, with Orion’s Belt pointing to it.

Bottom line: Use Orion’s Belt to find Sirius, the sky’s brightest star. In 2026, Jupiter is in the same region, outshining even Sirius.
