Comet Borrelly or Borrelly's Comet (official designation: 19P/Borrelly) is a comet with a period of 6.85 years that was visited by the Deep Space 1 spacecraft in 2001. The comet last came to perihelion (closest approach to the Sun) on 1 February 2022 and will next come to perihelion on 11 December 2028.

Deep Space 1 returned images of the comet's nucleus from 3400 kilometers away. At 45 meters per pixel, it was the highest resolution view ever seen of a comet up until that time.
Discovery The comet was discovered by Alphonse Borrelly during a routine search for comets at Marseille, France on 28 December 1904.
Exploration Deep Space 1 flyby
On 21 September 2001 the spacecraft Deep Space 1, which was launched to test new equipment in space, performed a flyby of Borrelly. It was steered toward the comet during the extended mission of the craft, and presented an unexpected bonus for the mission scientists. Despite the failure of a system that helped determine its orientation, Deep Space 1 managed to send back to Earth what were, at the time, the best images and other science data from a comet.
