The sun is defined as a star because it generates its own energy, a classification agreed upon by scientists over the past few centuries. While the sun's status is clear, other celestial objects, like Pluto, have faced reclassification as new discoveries challenge existing definitions. The International Astronomical Union (IAU) plays a crucial role in naming and classifying these objects. With advancements in telescope technology, such as the Vera C. Rubin Observatory, scientists may uncover new solar objects that could prompt a reevaluation of current classifications. This ongoing evolution in our understanding of celestial bodies highlights the dynamic nature of scientific inquiry.
