Below are some Interesting fact on Pluto from Wikipedia.Pluto, formal designation 134340 Pluto, is the second-largest known dwarf planet in the Solar System (after Eris) and the tenth-largest body observed directly orbiting the Sun. Classified as a planet from its 1930 discovery until 2006, Pluto is now considered the largest member of a distinct population called the Kuiper belt.Like other members of the Kuiper belt, Pluto is composed primarily of rock and ice and is relatively small: approximately a fifth the mass of the Earth’s Moon and a third its volume. It has an eccentric and highly inclined orbit that takes it from 30 to 49 AU (4.4–7.4 billion km) from the Sun. This causes Pluto periodically to come closer to the Sun than Neptune.].From its discovery in 1930 until 2006, Pluto was considered the Solar System’s ninth planet. In the late 1970s, following the discovery of minor planet 2060 Chiron in the outer Solar System and the recognition of Pluto’s very low mass, its status as a major planet began to be questioned.[9] Later, in the early 21st century, many objects similar to Pluto were discovered in the outer Solar System, notably the scattered disc object Eris, which is 27% more massive than Pluto. On August 24, 2006, the IAU defined the term “planet” for the first time. This definition excluded Pluto as a planet, and added it as a member of the new category “dwarf planet” along with Eris and Ceres. After the reclassification, Pluto was added to the list of minor planets and given the number 134340.A number of scientists continue to hold that Pluto should be classified as a planet.You might not understand everything here but these are facts that supported the delisting of Pluto
