Also known as Jordanus Fluvius or Jordanis, this constellation representing the river Jordan was introduced by the Dutchman Petrus Plancius on his celestial globe of 1612. He created it from the eight ‘unformed’ stars that Ptolemy had listed in the Almagest as lying outside the figure of Ursa Major. These stars are the modern Alpha and Beta Canes Venatici, Alpha, 31, and 38 Lyncis, and three others of uncertain identity (see here).
- New General Catalogue (Wikipedia)
The New General Catalogue of Nebulae and Clusters of Stars (abbreviated NGC) is an astronomical catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888. The NGC contains 7,840 objects, including galaxies, star clusters and emission nebulae. Dreyer published two supplements to the NGC in 1895 and 1908, known as the Index Catalogues (abbreviated IC), describing a further 5,386 astronomical objects. Thousands of these objects are best known by their NGC or IC numbers, which remain in widespread use.
- Jordanus (constellation)
Jordanus (the Jordan River) was a constellation introduced in 1612 (or 1613) on a globe by Petrus Plancius and first shown in print by Jakob Bartsch in his book Usus Astronomicus Planisphaerii Stellati (1624). One end lay in the present-day Canes Venatici and then it flowed through the areas now occupied by Leo Minor and Lynx, ending near Camelopardalis. This constellation was not adopted in the atlases of Johann Bode and fell into disuse.
