Jordanus Fluvius

The River Jordan

Unofficial Abbreviation: Jor
Genitive: Jordani Fluvii
Origin: Petrus Plancius

The extinct constellation of Jordanus Fluvius

In around 1612, Dutch astronomer and cartographer Petrus Plancius introduced a number of new constellations, including Jordanus Fluvius, the river Jordan. It is a northern constellation, with its headwaters near the star Cor Caroli and flowing through Leo and what are now Leo Minor and Lynx. However, a host of other faint constellations were placed in this general area by later cartographers and Jordanus dried up before the nineteenth century.
