- 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).
- Johannes Kepler (Wikipedia)
Johannes Kepler (/ˈkɛplər/; German: [joˈhanəs ˈkɛplɐ, -nɛs -]; 27 December 1571 – 15 November 1630) was a German astronomer, mathematician, astrologer, natural philosopher and writer on music. He is a key figure in the 17th-century Scientific Revolution, best known for his laws of planetary motion, and his books Astronomia nova, Harmonice Mundi, and Epitome Astronomiae Copernicanae, influencing among others Isaac Newton, providing one of the foundations for his theory of universal gravitation. The variety and impact of his work made Kepler one of the founders and fathers of modern astronomy, the scientific method, natural and modern science. He has been described as the “father of science fiction” for his novel Somnium.
