Clyde Tombaugh was the astronomer who discovered Pluto in 1930, while working at Lowell Observatory in Arizona. Tombaugh also found a comet, hundreds of asteroids, and several galactic star clusters.
Pluto was discovered on February 18, 1930 by Clyde Tombaugh at Lowell Observatory in Flagstaff, Arizona. It was discovered using two photographic plates taken of the same place in the sky on January 23 and 29.
Pluto was discovered in 1930 by American astronomer Clyde Tombaugh. It was considered the ninth planet in the solar system until 2006, when the International Astronomical Union reclassified it as a dwarf planet.
The symbol for Charon, the largest moon of the dwarf planet Pluto, is a combination of the letters "C" and "H." The "C" stands for "Charon" and the "H" represents the shared first initial of Pluto's discoverer, Clyde W. Tombaugh.

Pluto was discovered in 1930 by the astronomer Clyde Tombaugh. The existence of Pluto was predicted by perturbations of the orbit of Neptune late in the 19th century. Percival Lowell looked for it, and did photograph Pluto in 1915, but didn't recognize what he had seen. The task of finding the planet was given to Clyde W. Tombaugh at Lowell Observatory in Arizona. He did a very careful sky survey which identified Pluto in photos taken on February 18, 1930 and announced it on March 13, 1930
Pluto was discovered in 1930 by a lucky accident. It was predicted mathematically that there was a planet beyond Neptune. Not knowing this, Clyde W. Tombaugh at Lowell Observatory in Arizona did a very careful sky survey which turned up Pluto anyway.
