A two-lobed chunk of ice and dust, shaped like a rubber duck, and the first comet a spacecraft ever landed on.
67P is a Jupiter-family comet with a period of about 6.4 years. It has a distinctive shape made of two lobes joined by a neck.
ESA’s Rosetta spacecraft orbited it from 2014 to 2016, and its lander Philae made the first landing on a comet in November 2014.
