Pluto was reclassified as a dwarf planet from "summary" of The Secret World of Stargazing by Adrian West
Pluto, once considered the ninth planet in our solar system, found itself at the center of controversy when the International Astronomical Union made the decision to reclassify it as a dwarf planet. This decision, made in 2006, sparked debates among astronomers and space enthusiasts around the world. The reclassification of Pluto was based on new criteria set by the International Astronomical Union, which defined a planet as a celestial body that orbits the sun, is spherical in shape, and has cleared its orbit of other debris. Pluto met the first two criteria but fell short on the third, as its orbit overlaps with that of Neptune. As a result, Pluto was demoted from its planetary status and became known as a dwarf planet. This decision was met with mixed reactions, as many people had grown up learning about Pluto as the ninth planet in our solar system. Some argued that the reclassification was unfair, while others supported the decision, citing the need for a clear definition of what constitutes a planet. Despite the controversy surrounding its reclassification, Pluto remains a fascinating object of study for astronomers. Its distant location and unique characteristics make it a valuable subject for research, shedding light on the outer reaches of our solar system. As technology advances and our understanding of the universe grows, Pluto will continue to captivate our curiosity and spark new questions about the nature of our cosmic neighborhood.
