Pluto's Discovery Day!
On this day in 1930, astronomer Clyde Tombaugh made a groundbreaking discovery at the Lowell Observatory in Arizona. He identified what was then classified as the ninth planet from the Sun: Pluto. Tombaugh's meticulous search, using a blink comparator, revealed this distant celestial body. For over 70 years, Pluto was a planet, captivating imaginations as the outermost world. Although reclassified as a dwarf planet in 2006, its discovery marked a significant moment in our understanding of the solar system's vastness.
