For it was this unassuming farmer and astronomy enthusiast who, in 1930, peered into the depths of the night sky and forever changed our understanding of the solar system.
Tombaugh’s journey began in the humble town of Streator, Illinois. Inspired by the wonders of the cosmos, he built his own telescope at the tender age of 12. Little did he know that this childhood fascination would lead him to discover one of the most enigmatic and captivating celestial objects in our neighborhood.
In 1929, Tombaugh joined the team at Lowell Observatory, where he tirelessly analyzed photographic plates in search of a ninth planet that astronomer Percival Lowell had hypothesized to exist beyond Neptune. For several months, he meticulously compared images, looking for a tiny speck that moved from night to night.
On February 18, 1930, his perseverance paid off. In a plate captured by his mentor, Clyde Tombaugh noticed a faint, moving object that had eluded astronomers for years. It was Pluto, the long-awaited ninth planet.
Pluto’s discovery sent shockwaves through the astronomical community. It was a triumph for Lowell Observatory and a resounding affirmation of the power of persistence and human curiosity. Tombaugh’s legacy extended beyond his discovery. He continued to work at Lowell Observatory for many years, mentoring young astronomers and contributing to our understanding of the outer reaches of our solar system.

IAU Controversies: Pluto’s Shifting Status
In 2006, the world of astronomy was rocked by a cosmic bombshell: Pluto, once considered our ninth planet, was downgraded to the status of a dwarf planet. This decision by the International Astronomical Union (IAU) sent shockwaves through the scientific community and left many scratching their heads.
The IAU’s definition of a planet is simple: it must orbit the Sun, have enough mass to pull itself into a round shape, and clear its orbit of other objects. And here’s where Pluto stumbled. While it met the first two criteria, it failed to clear its orbit. That’s because Pluto’s cosmic neighborhood, the Kuiper Belt, is a crowded place, teeming with countless other icy objects.
Critics of the IAU’s decision argued that Pluto was just as deserving of planet status as the other eight planets. After all, it’s a large, spherical body that revolves around the Sun. But the IAU held its ground, explaining that if Pluto were reclassified as a planet, it would open the floodgates for other dwarf planets in the Kuiper Belt to join the celestial club.
The debate over Pluto’s status is a fascinating example of how science evolves. As we learn more about our solar system, our understanding of what constitutes a planet has also evolved. And who knows, in the future, the IAU may revisit its definition of a planet once again.

In the cosmic waltz of our solar system, Pluto and its mysterious moon, Charon, twirl together in a celestial pas de deux that has captivated astronomers and space enthusiasts alike.
Charon’s discovery in 1978 was a pivotal moment in our understanding of the Pluto-Charon system. This celestial duo is locked in a gravitational embrace, orbiting each other like a pair of cosmic ice skaters. But unlike most moons, which are mere echoes of their planets, Charon is almost as massive as Pluto itself, a celestial oddity that has earned it the distinction of being a “binary dwarf planet.”
Charon’s enigmatic nature extends beyond its size. The moon’s surface is a patchwork of bright and dark regions, hinting at a complex geological history. One of its most striking features is a vast, 930-mile-wide crater named Tombaugh Regio in honor of Pluto’s discoverer, Clyde Tombaugh. This colossal impact basin is thought to have been formed by a cataclysmic event early in Charon’s history.
The Pluto-Charon system is a dance of contrasts. While Pluto’s surface is dominated by the bright, icy plains of Sputnik Planitia, Charon’s landscape is characterized by a darker, more cratered terrain. This difference suggests that Charon has experienced a more turbulent geological past than its larger companion.
Beyond its physical attributes, Charon plays a crucial role in shaping the Pluto-Charon system. The gravitational pull between the two bodies creates tidal forces that have distorted their shapes into oblong spheroids. This dynamic interaction also creates a resonance between their orbits, ensuring that they always face the same side towards each other.
Charon is a celestial enigma that challenges our understanding of planetary systems. Its unique characteristics and intimate relationship with Pluto make it a fascinating object of study, offering a glimpse into the complexities of our cosmic neighborhood.
