No, Pluto has not been reclassified as a planet and as long as Eris is out there, bigger than Pluto, it will have to remain a dwarf planet, Captain Kirk.
The discovery of Eris was a main reason why Pluto was “declassified.” Otherwise, how many planets are we going to have to claim exist? Is Eris the 10th planet, bigger than Pluto? Did you know that Charon, Pluto’s moon, is so big that Pluto and Charon orbit each other? The center of gravity is outside the sphere of Pluto itself. Pluto is about the same size as our moon.
