Globus Aerostaticus, the Balloon, is a constellation invented by central European astronomers in collaboration in the late 18th century, used in Europe from 1801 to 1920. It is depicted in the area of [[Capricornus]], [[Piscis Austrinus]], and [[Microscopium]]. The word 'aerostat' in English, which means a balloon or airship. 

==Concordance, Etymology, History==
=== Origin of Constellation ===
Ian Ridpath (Star Tales, [http://www.ianridpath.com/startales/globusaerostaticus.html online edition])<ref>Ian Ridpath (1988). Star Tales, [http://www.ianridpath.com/startales/globusaerostaticus.html online edition]</ref> writes: <blockquote>This constellation first appeared on the ''Uranographia'' atlas of Johann Elert Bode in 1801, but it had been suggested to him in 1798 by the French astronomer Joseph Jérôme de Lalande (1732–1807) who wanted to honour the hot-air balloon invented in the 1780s by the Montgolfier brothers. The balloon floated in the sky south of the zodiacal constellation Capricornus, next to the tail of Piscis Austrinus, the southern fish, which was shortened to accommodate it. In his Histoire Abrégée de l’Astronomie, Lalande recalled that Nicolas Louis de Lacaille had placed instruments of science and arts among the stars of the southern hemisphere, and explained: ‘I thought the greatest discovery of the French deserved to occupy a place’.</blockquote>‍<blockquote>‍Lalande put his suggestion to Bode at an international astronomical congress held in August 1798 at Gotha, Germany. Bode accepted Lalande’s idea, but in return took the opportunity to propose a constellation of his own to represent Gutenberg’s printing press; this became Officina Typographica. At the time of the Gotha conference Bode had reached Chart XV of his atlas. The hot air balloon appeared on Chart XVI, and the printing press on Chart XVIII. History shows that the printing press has been more influential than the hot-air balloon, but neither remain among the recognized constellations.</blockquote>‍<blockquote>‍Its brightest star, which Bode labelled with a lower case ‘a’ (but looking like a Greek alpha) on his chart in ''Uranographia'' (below), was of only magnitude 4.7. This star was originally catalogued by Flamsteed as part of Piscis Austrinus. It has since been transferred to the adjacent Microscopium, where it is known as Epsilon Microscopii; Bode’s Epsilon Microscopii is now left unlettered.</blockquote>

At the opening ceremony of the Olympic Games in Paris (2024), a modern "mongolfiere" was launched as part of the show (see [https://www.olympics.com/en/news/paris-2024-olympic-flame-takes-centre-stage IOC page]).

== IAU WGSN Name Discussion ==
The name "Globus Aerostaticus" was suggested as a star name to WGSN in 2023. As names must have only 16 characters maximum, the abbreviated name "Aerostaticus" is considered as a modern star name to resemble this historical constellation.
