107P/4015 Wilson-Harrington is one of the most intriguing objects, being known for having a cometary history as well as Near Earth Object characteristics, which could answer questions regarding both the origin of life and formation and evolution of small bodies. We first briefly summarize the knowledge state of this small body, leading to its actual classification. We then look at its main dynamical characteristics to prepare for a near future rendezvous and sampling mission, and we make comparisons between the target of the Rosetta mission, 67P/Churyumov-Gerasimenko, for which the spacecraft is carrying a lander, and the targets of Hayabusa and of the Hayabusa Follow-on Mission, Itokawa and 1999 JU3. Finally, we investigate the local stability properties in both proximity of the target and on the surface, and show simulations, to discuss approach strategies.
