Friedrich Wilhelm Bessel (German:; 22 July 1784 – 17 March 1846) was a German astronomer, mathematician, physicist, and geodesist. He was the first astronomer who determined reliable values for the distance from the sun to another star by the method of parallax .
Mar 13, 2024 · Friedrich Wilhelm Bessel, German astronomer whose measurements of positions for about 50,000 stars and rigorous methods of observation took astronomy to a new level of precision. He was the first to measure the parallax, and hence the distance, of a star other than the Sun. Learn more about Bessel’s life and work.

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. He was the first to measure (by means of parallax) the distance to a star other than the Sun. One of his major discoveries was that the bright stars Sirius and Procyon make tiny motions explainable only by the ...
The work of the German astronomer and mathematician Friedrich Wilhelm Bessel (1784 –1846) provides a good illustration. Among his many other accomplishments, Bessel developed techniques to measure the positions of stars with far greater accuracy than previously possible.
