Rosetta: What comet would look like over Europe's biggest cities
After a historic but awkward comet landing, the robot probe Philae is now stable and sending pictures.
The probe is around the size of a washing machine and it is hoped it will explore the 4km wide comet, so scientists can learn more about the origins of our Solar System.
To get a sense of the scale of 67P/Churyumov-Gerasimenko, the European Space Agency has released a set of images which compare it with some of the largest cities in Europe.
