what is the meaning of Puppis?

"Puppis" is the name of a constellation in the southern hemisphere. It represents the stern (rear part) of the ship Argo Navis.

Here's a breakdown:

* Puppis: Latin for "stern"

* Argo Navis: A legendary ship in Greek mythology, captained by Jason and the Argonauts in their quest for the Golden Fleece.

Historically, Argo Navis was a single, enormous constellation. However, it was divided into three smaller constellations in the 18th century:

* Puppis: The stern

* Carina: The keel

* Vela: The sails

So, Puppis is the "stern" of the mythical ship Argo Navis, and the name directly reflects its representation in the sky.
