The discoverers of Kapteyn's Star

| Jacobus Kapteyn and Robert Innes discovered Kapteyn's Star — originally named "Cordoba Zone 5 hours 243" because of its location — in 1897. Kapteyn was in Holland analyzing photographic plates taken at the Cape Observatory in South Africa, and Innes was an assistant at the Cape Observatory. Kapteyn did not find a star in its documented location and asked Innes to look for it in the sky. Innes found the star, but it was east of where it should have been. They had discovered the fastest moving star in the sky (the record, however, has since been broken by Barnard's Star). |
