this inconspicuous binary star, recognizable even with a smaller telescope, is famous for being the first to have its trigonometric parallax measured in 1838 - the distance of this constellation was determined by the German astronomer Friedrich Wilhelm Bessel (he worked mainly in astrometry - he measured precisely the positions of over 50,000 stars and predicted the presence of their long-invisible guides in 1844 on the basis of an analysis of the irregular proper motion of the magnitude and Procyon). |
