Pluto Stickers
Description: In 1906, Percival Lowell—a wealthy Bostonian who had founded Lowell Observatory in Flagstaff, Arizona, in 1894—started an extensive project in search of a possible ninth planet, which he termed "Planet X. Once Pluto was found, its faintness and lack of a viewable disc cast doubt on the idea that it was Lowell's Planet X. Estimates of Pluto's mass were revised downward throughout the 20th century.
Description: Pluto was found in 1930 and was thought to be the ninth planet from the Sun at the time. For the first time, the International Astronomical Union (IAU) released an official definition of "planet" in 2006.The choice was very contentious at the research center, which is situated in Flagstaff, Arizona. This is also because it is the location of the original discovery of Pluto by American astronomer Clyde W. Tombaugh on February 18, 1930, a day commemorated yearly as International Pluto Day.Are you familiar with the planet Pluto? Purchase this t-shirt right now to memorialize it.
