Marian Albertowitsch Kowalski ( Russian Мариан Альбертович Ковальский ; born August 15, 1821 or October 15, 1821 in Dobrzyń , Poland ; † May 28, 1884 or July 9, 1884 in Kazan ) was a Polish - Russian astronomer .

He studied at the University of Saint Petersburg . From 1852 he was the director of the observatory and dean of the Faculty of Physics and Mathematics in Kazan .

His most important work was the analysis of the proper motion of 3136 fixed stars from the star catalog of James Bradley . This was the first applicable method to infer the rotation of the Milky Way . Based on this work, he refuted the view that a single massive body in the center of our galaxy was responsible for the movement of the stars.

In the field of celestial mechanics , he developed improved methods for inferring the orbit of a planet from observations, and he analyzed the mathematics of perturbations in planetary motion. In particular, he made a more accurate determination of the orbit of the planet Neptune . He also created an improved method for determining the orbits of binary stars .

His most important writings were published in 1859 under the title Recherches astronomiques de l'observatoire de Kazan .

He is buried in the Catholic cemetery in Kazan.

The Koval'sky craters on Mars and the Koval'skiy craters on the moon have been named in his honor.
