The constellation Southern Fish (lat. Piscis Austrinus) contains the strikingly bright star of the first magnitude "Fomalhaut". The name origins in the Arabic description "Fum al Hut", "mouth of the fish". It is orbited by a planet whose mass is about eight times that of Jupiter. The constellation itself, however, is relatively inconspicuous.
How to spot Piscis Austrinus
With an area of 245 square degrees, Piscis Austrinus extends in the southern hemisphere. North you can find the constellations Aquarius and Capricornus. To the west is the Microscopium, to the east the Sculptor and to the south Grus. It is best to look at it during the summer.
Piscis Austrinus already existed before Pisces, in the 8th century BC. Greek astronomers recognized the constellation in the form of a fish in the sky. In the Babylonian age, the Fertility God Oannes was seen in it. Later, Ptolemy included it in his description of the 48 constellations of antiquity.
