Are Quaoar and Pluto going to crash into each other?
No, it kind of looks like it from the picture above of the orbits, but they don’t collide, Quaoar’s orbit is tilted with respect to the other planets by about 8 degrees. Pluto is tilted by about 20 degrees, so although it looks like they might hit each other from the “top view”, a “side view” would show that their orbits don’t intersect.
