Why is there a argument about Pluto the planet.
There's an argument about Pluto the planet because some people say that Pluto should not be part of our solar system and not be considered a planet due to it's size but other people think it should remain a planet.
There have been various answers to this on here. You could try a Search to find them.
The argument about Pluto's planetary status stems from a change in the definition of a planet made by the International Astronomical Union (IAU) in 2006. Prior to this change, Pluto was widely accepted as the ninth planet in our solar system. However, the IAU redefined what constitutes a planet and introduced a new category known as "dwarf planets."
According to the IAU's definition, a planet must meet three criteria: it must orbit the Sun, it must be spherical in shape, and it must have cleared its orbit of other debris. While Pluto meets the first two criteria, it fails to meet the third one. As it shares its orbital path with other objects in the Kuiper Belt, Pluto is considered to be part of a larger population of icy bodies rather than a dominant object in its own orbit.
This reclassification of Pluto generated disagreement among scientists and the general public. Those who argue in favor of Pluto being a planet often point to its historical recognition as a planet and the emotional attachment that people have developed for it. On the other hand, proponents of the new definition stress the importance of scientific precision and categorization based on specific criteria.
