Jacobus Kapteyn was a Dutch astronomer known for his contributions to understanding the structure and motion of our galaxy, the Milky Way. He developed methods to map star distributions and their movements, helping to reveal the galaxy’s shape and size. By studying how stars are arranged and how they move, Kapteyn contributed to our knowledge of the galaxy's dynamics and our place within it. His work laid important groundwork for modern astrophysics and improved our understanding of the universe's large-scale structure.
