Abstract :

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 (67P/CG)

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, I will discuss some ways to

reconcile some of the puzzling aspects of 67P/CG with the recent progress made in

understanding the formation of planetary systems from the study of exoplanets.
