PDE Q127
0. Which among the following planets intersects the orbit of Neptune?
- Option : B
- Explanation : Pluto's orbit is in a 3:2 resonance with Neptune's. This puts Neptune far from Pluto whenever Pluto is inside of Neptune's orbit. A non-resonant configuration would not be stable and would likely see Pluto ejected from the solar system within several thousands of orbits. So the answer is (B)
