Piscis Austrinus, which is Latin for "the southern fish," is one of the original 48 constellations described by Greek astronomer Ptolemy in the 2nd century.

Originally known as "the Fish" by the Babylonians, it was introduced to the Greeks around 500 BC. In Greek mythology, this is "the Great Fish," swallowing the water being poured out by Aquarius. The two fish of Pisces are its offspring.

There are two named stars here:

Fomalhaut (α Piscis Austrini) is the brightest star in this constellation and the 18th-brightest star in the night sky. It is a triple star system, consisting of a blue-white giant, and two red dwarfs. The entire system lies about 25 light years away. Fomalhaut is notable for being surrounded by several "debris disk," disks of dust that might be forming planets. Its name comes from the Arabic phrase fam al-ḥūt meaning "the mouth of the fish."

Sāmaya (HD 205739) is a Sun-like star about 303 light years away. It has one confirmed exoplanet orbiting it, about 1.3 times the mass of Jupiter, named Samagiya. Both names were given by the people of Sri Lanka: Sāmaya means "peace" in the Sinhalese language, while Samagiya means "togetherness" or "unity".
