Tuesday marks the tenth anniversary of a huge astronomical milestone: the first and only time we have landed on a comet.
The Rosetta probe’s lander Philae landed on Comet 67P/Churyumov-Gerasimenko on 12 November, 2014, after a decade spent travelling nearly 4 billion miles through space.
Having left Earth in 2004, Rosetta approached the orbit of Comet 67P/Churyumov-Gerasimenko on its looping path in and out of the asteroid belt, before finally entering into orbit around the comet itself in August 2014.
