Astronomers Answer When Will Pluto Collide With Neptune

Pluto's weird orbit was one of the main reasons why it got demoted to the status of a dwarf planet. Three things about its orbit make it an oddball among the planets: Firstly, it's highly inclined to the ecliptic. Pluto's inclination to the ecliptic is 17º, way more than any planet in the solar system. Secondly, the orbit is highly elliptical. And finally, it takes Pluto a whopping 248 Earth years to complete one revolution around the Sun.
