Giotto was an unmanned space mission from the European Space Agency, intended to fly by and study the Comet Halley. On March 13, 1986, Giotto approached to a distance of 596 kilometers of Halley's nucleus.
Giotto also flew by the Comet Grigg-Skjellerup, which it approached to a distance of ca. 200 kilometers.
The spacecraft was named after the medieval painter Giotto di Bondone from Italy. Giotto di Bondone painted the star of Bethlehem as the Halley's comet.
