There isn't a single "first star" you see in the southern hemisphere, as the visibility depends on your location, time of year, and light pollution. However, some of the brightest and most recognizable stars in the southern hemisphere include:

* Sirius (Alpha Canis Majoris): The brightest star in the night sky, located in the constellation Canis Major.

* Canopus (Alpha Carinae): The second brightest star in the sky, located in the constellation Carina.

* Alpha Centauri: The closest star system to our own sun, composed of three stars (Alpha Centauri A, Alpha Centauri B, and Proxima Centauri).

* Achernar (Alpha Eridani): The ninth brightest star in the sky, located in the constellation Eridanus.

* Rigil Kentaurus (Alpha Centauri A): The brightest star in the constellation Centaurus.

These are just a few examples. There are many other bright and beautiful stars visible in the southern hemisphere, and observing them can be a truly awe-inspiring experience.
