Pluto's Demotion: Why it Lost Planet Status in 2006

Описание: Latest space exploration and astronomy discoveries: Remember Pluto as the ninth planet? In 2006, the International Astronomical Union made a controversial decision, reclassifying Pluto forever. Discover why this happened and its lasting impact on space science. This video dives into the fascinating controversy surrounding Pluto's demotion from a full-fledged planet to a dwarf planet. We'll explore Clyde Tombaugh's 1930 discovery, the emergence of the Kuiper Belt, and the critical discovery of Eris, which ultimately forced astronomers to rethink our solar system's definition. Learn about the crucial 2006 IAU vote in Prague, the three new criteria for planetary status, and why Pluto failed to clear its orbital neighborhood. Understand the ongoing debate and the profound implications of this reclassification for astronomy and how we teach about the cosmos.
