Comets are very interesting for planetology as well as for exobiology. On one hand, held in the furthest and coldest regions of our solar system and due to their small size, they might not have been altered since their formation. The study of comets should allow a better understanding of the physic-chemical processes occurring during the Solar system formation. On the other hand, the analysis performed in 1986 on the environment of 1P/Halley showed the presence, in the cometary dust, of organic matter. Thus, comets might have brought organics on primitive Earth which might have contributed to the apparition of life. Nevertheless, the nature of these organics is still not well-known. Cometary organics might have been synthesized from the ice...
