On July 2, 1985, the European Space Agency launched the Giotto space probe to get a close-up look at Halley’s Comet.
Nearly nine months after launch, on March 14, 1986, Giotto became the first spacecraft to observe of a comet up close when it flew by Halley’s Comet.
It came within 370 miles of the comet’s surface.
Giotto was named after the early Renaissance painter Giotto di Bondone, who had depicted Halley’s Comet as the star of Bethlehem in his painting, Adoration of the Magi.
