How is iau different from a dwarf planet?

The International Astronomical Union (IAU) is an organization responsible for the classification and naming of celestial bodies, including planets and dwarf planets. A dwarf planet, on the other hand, is a specific category of celestial body defined by the IAU, characterized by its orbit around the Sun, sufficient mass for a nearly round shape, and inability to clear its orbital path of other debris. In essence, the IAU establishes the criteria for what constitutes a dwarf planet, while the term "dwarf planet" refers to a type of object that fits within those criteria.
