Jun 27, 2018 · Bessel, Friedrich Wilhelm (1784–1846) German astronomer and mathematician. Bessel devised a system for analysing and reducing astronomical observations, made the first accepted measurements of the distance of a star (61 Cygni), and accurately predicted that Sirius and Procyon are binary stars.
Friedrich Wilhelm Bessel, (born July 22, 1784, Minden, Brandenburg—died March 17, 1846, Königsberg, Prussia), German astronomer.
