Ep 232: We remember you! - Pluto (formerly the planet)
In this episode, we embark on a cosmic journey to explore the fascinating history of Pluto, the celestial body that once held the title of the ninth planet in our solar system. With its heart-shaped surface and icy landscapes, Pluto has captured the imagination of astronomers and the public alike. However, in 2006, it was reclassified as a dwarf planet, sparking debates and nostalgia for those who grew up learning about it as a planet.
Our hosts delve into the early 20th century, where the quest to discover "Planet X" began. Percival Lowell, a wealthy Bostonian and astronomer, established the Lowell Observatory and dedicated his life to finding this elusive planet, which was believed to be causing disturbances in Neptune's orbit. After his passing, the task fell to Clyde Tombaugh, a young observatory assistant who, through painstaking efforts, finally discovered Pluto in 1930.
As we uncover the whimsical story of Pluto's naming—thanks in part to an 11-year-old girl—we also discuss its unique characteristics. Unlike other planets, Pluto's orbit is highly elliptical and tilted, and it has a moon, Charon, that is nearly half its size. This peculiar relationship between Pluto and Charon leads to their classification as a "double planet."
However, the discovery of other icy objects in the Kuiper Belt, including Eris, led to a reevaluation of what constitutes a planet. The International Astronomical Union's decision to demote Pluto to a dwarf planet sparked public outcry and nostalgia, as many felt a deep connection to this once-beloved planet.
Throughout the episode, our hosts reflect on the implications of Pluto's reclassification and the broader understanding of our solar system. As science continues to evolve, so too does our understanding of celestial bodies. Join us as we celebrate Pluto's rich and chaotic history and ponder the mysteries of the universe that lie beyond our reach. Tune in now and discover why Pluto will always hold a special place in our hearts!
