Rosetta had to travel 6 billion kilometers to arrive at the comet. Rosetta passed in front of the Earth, Mars and 2 asteroids with the gravity . The name of the comet is 67P/Churyumar-Gerasimenka because it has been discovered by 2 Russians scientists. The mission of Rosetta is to learn more about the comet. Lots of people have always been interested in comets or afraidby them. It's the most difficult mission ever done because the speed of the comet is 40 000 km/h like the speed of a bullet.
