In 1959 67P changed orbit after a very close ecnounter with Jupiter. Numerical simulations show a close aproach distance between 0.040 and 0.020 AU (depending if you are considering or not deviations due to the push performed by cometary jets). Considering that Callisto orbits Jupiter at 0.012AU this had to be an epic vista.
The video shows a model of dust ejection by the comet where each perihelion pass is colored with different colors. As time goes on, the dust of the comet get's caotically distributed around the orbit and the inner planets start to generate a complex cloud.
As you can see, Mars is going to have new amazing meteor showers produced by Rosetta's comet the next decades.
After the encounter 67P acquiered its current orbit (September this year it's going to change again a little by anothe Jupiter encounter)
I leave you with this awesome timelapse taken by Rosetta. Each frame is a long-exposure image taken of the neck of the comet (when it was in shadows). You can see the neck because daylight bounces in different parts of the comet making a pale reflection on this region. In the background you can see the stars (even a globular cluster shows up). And in the front you are watching dust grains as they pass in front of the camera.
. Don't be fooled by the title of this lecture, it's not a psuedoscienctific rant. I found the end conclusion to be much more eloquent.
