This coin celebrates the Mykolaiv astronomical observatory, a research and development center. One of the oldest observatories in Eastern Europe, it was founded in 1821 as a marine observatory, with a view of providing the Black Sea Fleet with maps, and teaching naval officers methods of astronomical orientation. The observatory was involved in doing an important astronomical task – creating a celestial fundamental coordinate system. This was done through the joint efforts of observatories across the world to produce fundamental catalogues on the basis of millions of separate observations and the measurement of the positions of stars for almost 200 years. Today, the observatory mainly studies near-Earth objects and the movements of Solar System bodies, creates astrometric catalogues of stars, provides information support for astronomical research, and makes astronomical instruments.
