Comets have always been thought as relics from the early days of the solar system. ESA ’s Rosetta mission by following the comet 67P/Churyumov-Gerasimenko along its trajectory, delivered for the first time not just a snapshot in time of a comet nucleus but its full time dependent evolution as it approached the sun. Just like the stone that gave the name to the mission, the wealth of data recorded provides a unique opportunity to help decipher the 4.5 billion yearlong story of the solar system. It turns out that the book is not so easy to read! In this talk, we will show that when these data are coupled with the many progresses made over the past few years in particular due to the discovery of exoplanets, a consistent scenario reconciling many aspects of the problem is slowly emerging.
