WebbOort cloud comets become observable from Earth when their perihelion distances become small due to external forces. For example, when a star penetrates the Oort cloud, the star drills a nar- row tunnel through the Oort cloud by ejecting the comets within some distance from the star as described in Figure 1. Webb10 nov. 2015 · What makes the inner Oort cloud objects interesting is that their eccentric orbits cannot be explained by the known structure of the solar system: Something else had to perturb their orbits. Possible explanations include an unseen giant planet that still orbits in the deep or one that was ejected from the solar system, disturbing inner Oort cloud …
