Who discovered Pluto? Clyde Tombaugh, an American astronomer, discovered Pluto on February 18, 1930.
Pluto is a dwarf planet located in the Kuiper Belt, a region of icy bodies beyond Neptune. It was originally classified as the ninth planet from the Sun, but was reclassified as a dwarf planet in 2006 by the International Astronomical Union (IAU).
Tombaugh discovered Pluto while working at the Lowell Observatory in Flagstaff, Arizona. He was using a photographic plate taken by Percival Lowell, the founder of the Lowell Observatory, to search for a ninth planet. Tombaugh compared two photographic plates taken on different nights and found an object that had moved. He then took more photographs of the object and confirmed that it was a new planet.
Tombaugh named the new planet Pluto after the Roman god of the underworld. Pluto is a small, icy world with a diameter of about 2,300 kilometers (1,400 miles). It has a thin atmosphere and a surface that is covered in ice and nitrogen.
Pluto is a fascinating world that is still being studied by scientists. It is a reminder that there is still much that we do not know about our solar system.

Importance of Pluto's Discovery
The discovery of Pluto was important for several reasons. First, it confirmed the existence of a ninth planet in our solar system. Second, it helped to define the outer limits of our solar system. Third, it led to the discovery of other dwarf planets in the Kuiper Belt.
Pluto's discovery also had a cultural impact. It captured the public's imagination and helped to popularize astronomy. Pluto was even featured in a number of movies and television shows.
Challenges in Discovering Pluto
Tombaugh faced a number of challenges in discovering Pluto. First, he had to find a way to distinguish between real objects and photographic artifacts. Second, he had to track the object over several nights to confirm that it was moving.
Tombaugh also had to deal with the skepticism of some astronomers. Some astronomers believed that Pluto was too small to be a planet. Others believed that it was not a planet at all, but rather a comet or an asteroid.
Despite these challenges, Tombaugh was able to prove that Pluto was a new planet. His discovery was a major milestone in astronomy and helped to expand our understanding of the solar system.
