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 .
Apr 17, 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.

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.
Jul 22, 2011 · Bessel published Bradley 's stellar positions in 1818 in a work which gives the proper motion of stars. In 1825 he was honoured by election as a Fellow of the Royal Society . In 1830 Bessel published the mean and apparent positions of 38 stars over the 100 year period 1750-1850. These 38 stars were the 36 'fundamental stars' of Maskelyne ...
