The International Astronomical Union (IAU) classifies objects in our solar system into several categories based on their characteristics. These include planets, dwarf planets, moons, asteroids, comets, and meteoroids. The classification primarily considers factors like size, shape, and orbital dynamics, as well as the object's ability to clear its orbit of other debris. This system helps in organizing and understanding the diverse range of celestial bodies within our solar system.

What is the organization that decides the status of planets?
The International Astronomical Union (IAU) is the organization responsible for officially classifying celestial bodies, including planets. They determine the criteria that define what constitutes a planet and ultimately decide on the status of objects in our solar system.

According to those who do not accept the IAU's judgement on such matters - and no one is required to - Pluto. While Pluto was declared by the IAU to no longer be a planet, many disagreed. They had - and have - that right.
Since 2006 what has Pluto been classified as in the Solar System?
Pluto has been classified as a dwarf planet in the Solar System since 2006. This reclassification was made by the International Astronomical Union (IAU).
What is the name of the object in your solar system that is now called a dwarf planet?
It is planet Pluto. ______________________ There are five "dwarf planets" in our solar system, as of August 2010. There are certainly dozens or hundreds more in the distant parts of our solar systems, but our telescopes are not yet good enough to see them. Pluto was considered a planet until the International Astronomical Union (IAU) reclassified it. Ceres was an asteroid before the IAU reclassified it. The Kuiper Belt Objects later named Eris, Haumea and Makemake were all considered to be candidates for being named the "Tenth Planet" until the IAU came out with its definition of "planet". In fact, it was the discovery of the dwarf planet Eris, originally called "Xena", that caused the IAU to finally come up with a formal definition of "planet". All three of these objects are now considered to be "dwarf planets". There are several other large asteroids that probably deserve "dwarf planet" status as well; Vesta, certainly, and Pallas, and perhaps a few others.

Why do they call them dwarf planets?
The new designation 'dwarf planet' for Solar System objects was decided in 2006 by the International Astronomical Union (IAU), which has jurisdiction over the classification and naming of astronomical bodies. Because more Pluto-sized objects were being located in its area of the solar system (the Kuiper Belt), the IAU decided to limit "planet" status only to the eight large bodies that dominate their respective orbital areas, as far out as Neptune. So the potential for a constantly-changing and contentious count of 'planets' would be avoided (reminiscent of the "moons of Jupiter", which were classically 12 but now number 63).
