Observations of the Comet 67P, from the ESA Rosetta satellite, show that the comet appears to be slowing down. Rosetta flight director, Andrea Accomazzo, explains: “The gas jets coming out of the comet, are acting like thrusters and are slowing down the comet. The aerodynamic effects are now more and more important. The jets are getting stronger and stronger.”

She adds, “To give you an idea, these gases come out of the comet for a few kilometres and are moving at 800 metres per second.”
