This small and relatively faint constellation could be misidentified as being named for an ant, but Antlia Pneumatica is the water pump to most astronomers. In Germany it is called the Luft Pumpe. Generally, in most lists of constellations in all languages it is called more simply Antlia, a name given to in in the 18th century by Abbé Nicolas Louis de Lacaille.   Antlia lies south of Hydra and Crater and is near Vela, the sail of Argo Navis. It has eighty-two naked eye stars and can be seen from Fort Lauderdale, Florida during spring break. , the sail of Argo Navis. It has eighty-two naked eye stars and can be seen from Fort Lauderdale, Florida during spring break.  

HD 93083 is a K3V type orange hued star in the Antlia Constellation. In 2005 it was discovered that this 8.3 magnitude has a planetary system which lies within the “Habitable” range of the star. The star was designated as Macondo and the planet circling the star was named Melquíades by the IAU after a character in the book Cien años de soledad (One Hundred Years of Solitude) during the IAU’s NameExoWorlds Campaign in June 2019.

History of the Constellation Antlia 

Although the stars have shone overhead for centuries and have been identified by many cultures, Antlia resides in a southern area of the sky that was catalogued by French astronomer Abbé Nicolas Louis de Lacaille in the 18th century. Lacaille’s extensive collection Coelum Australe Stelliferum, was published in 1763, after his death.  Unlike many constellations which were named by the early Greeks and Romans, this grouping of 14 faint constellations was given names associated with inanimate objects like the furnace the table, the microscope and others. Best time to see it is during the spring season and this once can be seen south of Hydra constellation and between constellations Centaurus, Vela and Compass, when the night sky is clear and bright. 

Antlia is the first constellation alphabetically in the group of constellations named by de Lacaille. The other constellations in this group also lie in the same area of the southern sky. They include Caelum, Circinus, Fornax, Horologium, Mensa, Microscopium, Norma, Octans, Pictor, Reticulum,Sculptor, and Telescopium.
