| Beschrijving keerzijde | The right-facing portrait bust of Johannes Kepler dominates the right portion of the field, rendered in a bold, detailed relief with a full beard and period costume. To the left, an astronomical diagram illustrates one of Kepler's laws of planetary motion, depicting an elliptical orbit with geometric construction lines, a sun symbol, and notations referencing his mathematical formulations. Wavy lines at the base of the diagram suggest a cosmological or terrestrial context. The three-line legend 400 JAHRE KEPLERSCHE GESETZE appears in the lower field, commemorating the 400th anniversary of the publication of Kepler's laws. |

| Aanvullende informatie |
Issued to mark the International Year of Astronomy, this coin commemorates the 400th anniversary of Johannes Kepler's publication of Astronomia Nova in 1609, in which he established his first two laws of planetary motion. Kepler derived those laws not from new observations but from Tycho Brahe's meticulous naked-eye data — records Kepler had effectively acquired under disputed circumstances following Brahe's death in 1601.
Germany's commemorative 10 Euro silver program of this period was produced for collectors rather than circulation, with the Bundesbank distributing issues through face-value sales at post offices and banks.
