Pluto: Planet or dwarf planet?

Pluto is a planet discovered on February 18, 1930 by an American astronomer. It was regarded as the ninth planet until 2006, when its classification was changed to a dwarf planet. Pluto takes about 248 years to orbit the sun. Since it was discovered, it only completely about one third of its orbit! In 2003, an astronomer discovered Eris, another dwarf planet. Pluto is an icy and extremely cold planet since it is very far from the sun. The weird thing about that was Eris was bigger than Pluto. This led astronomers to question what makes a planet a planet. They decided that Pluto is too smaller to be classified as a planet, so in 2006, it and some other objects were classified as dwarf planets. There is big controversy on this topic. Do you think that it is a dwarf planet or a planet?
