Tombaughs

Tombaughs refers to the celestial objects discovered by Clyde Tombaugh, an American astronomer. His most famous discovery is Pluto, which was initially classified as a planet. Tombaugh's work was instrumental in the early exploration and understanding of the outer solar system. He utilized a blink comparator, a device that allowed him to compare photographic plates of the sky taken at different times, to detect objects that had moved against the background stars. This method led to the identification of numerous asteroids and other minor planets in addition to Pluto.

The search for Planet X, a hypothetical planet beyond Neptune believed to be responsible for perturbations in the orbits of Uranus and Neptune, was a major driving force behind Tombaugh's discovery of Pluto. While Pluto was found, it was later reclassified as a dwarf planet in 2006 by the International Astronomical Union due to new discoveries of similar-sized objects in the Kuiper Belt. Tombaugh's dedication to meticulous observation and his innovative use of technology significantly contributed to our knowledge of the solar system's distant regions. His legacy is honored by the naming of the Tombaugh Regio, a large, heart-shaped feature on Pluto.
