Pluto was considered as the ninth planet of our solar system for about 70 years. In 2006, International Astronomical Union (IAU) reclassified it as the dwarf planet. As of today, there are five dwarf planets in our solar system i.e: Pluto, Eris, Haumea, Makemake, and Ceres. Pluto being the biggest among them followed by Eris in fact, they are almost of the same size. Below are some interesting Pluto facts you may enjoy!
