Puppis
The ship's stern sailing winter skies
Best on December–February evenings · southern sky.
Puppis is the Stern of the ancient celestial ship Argo, a large sprawling constellation that stretches through a rich stretch of the winter Milky Way. It sits in the southern sky, bordering the more famous Canis Major, and rewards anyone who pushes past Orion's familiar shapes to explore further south.
How to find it
Best seen on winter evenings from the southern hemisphere, and from the northern hemisphere's southern horizon through December into February. Start at brilliant Sirius in Canis Major — the brightest star in the sky — then sweep southeast; the bright, slightly blue-white point you hit is Naos, the heart of Puppis. The constellation fans out from there into the Milky Way's star fields.
Brightest stars
Naos (ζ Pup) leads at magnitude 2.25, one of the most luminous stars known, and Tureis (ρ Pup) follows at magnitude 2.81. Azmidiske (ξ Pup) at magnitude 3.34 rounds out the trio of named stars.
Worth seeing
The region around Naos drifts through a dense lane of the Milky Way, so even slowly sweeping the area with binoculars reveals a stunning carpet of background stars that makes the stern of the old ship feel genuinely vast.
Frequently asked
When is Puppis visible?
Winter evenings, roughly December through February, when it climbs into the southern sky. Southern hemisphere observers get the best view; northern observers can catch it low on the southern horizon from mid-latitudes.
What are the brightest stars in Puppis?
Naos (magnitude 2.25) is the standout, followed by Tureis at 2.81 and Azmidiske at 3.34 — three named stars anchoring a large, star-rich constellation.
Which hemisphere is Puppis best seen from?
The southern hemisphere, where it rides high in the winter sky. Northern hemisphere observers can spot the brighter stars low in the south on clear winter evenings, but the full constellation never climbs very high.
