'''589 Croatia''' is a [[minor planet]] orbiting the [[Sun]], discovered by [[August Kopff|Dr. August Kopff]] from [[Landessternwarte Heidelberg-Königstuhl|Königstuhl-Heidelberg]] Observatory, with the use of the photographic method. In the moment of the discovery, the asteroid was 12,5<sup>mv</sup> and was in the constellation of Virgo. The object was named [[Croatia]], after the suggestion made by professor [[Max Wolf]], to honor the foundation of the [[Astronomical Observatory of the Croatian Natural Sciences Society ]] in [[Zagreb]]. The discovery was published in the ''[[Astronomische Nachrichten]]'' magazine, in the article wrote by Professor Wolf. Later, some astronomers ([[Johann Palisa]], [[K. Lohnert]] and some others) were making mesurements for the purpose of determining the [[orbital elements]]. From these measurements [[P.V. Neugebauer|Dr. P.V. Neugebauer]] from [[Berlin]] and [[M.S. Mello]] and [[Simas]] from [[Trafaria]] ([[Lisboa]]) had independently determined the first orbital elements. Observations had continued, and among observers there were A. Kopff, [[E. Bianchi]], [[A. Abetti]], [[G. Zappa]], [[P. Chafardet]], [[E. Millossevich]], J. Palisa, and some others. Observations were made from [[Berlin]], [[Copenhagen]], [[Rome]], [[Arcetra]] and some other [[Italy|Italian]] cities. The radius of (probably) 28,452 km (and, consequently, the superficial area of 2543,2 km<sup>2</sup>, and equatorial circumference of 89,385km) were determined by the use of [[Argelander's Method]].
