About the Discovery of Pluto

Pluto was discovered on February 18, 1930. The search for it was inspired by Percival Lowell, a man ridiculed for his belief in Martians. The discovery is explained by astronomer and author Ken Croswell in an interview with EarthSky.

�In 1929, Lowell Observatory hired a young man from Kansas, by the name of Clyde Tombaugh. And he implemented a search for Pluto. Tombaugh was using a telescope that took photographic plates of the sky. During the day, he would examine those photographic plates for a moving object. The word �planet� actually means �wanderer,� something that moves night-to-night in the way that stars don�t.

�On February 18, 1930, a little after 4 p.m. Mountain Time. He saw Pluto for the very first time. And his first words to himself were, �That�s it!�

�The discovery of Pluto was inspired by Percival Lowell, and is a testimony to the hard work that Clyde Tombaugh put into searching millions of stars to find this tiny, faint object in space.�
