Friedrich Wilhelm Bessel ( German: [ˈbɛsl̩]; 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.
