Meet your educator in the iconic Rotunda Building to learn about the groundbreaking discovery that put Lowell Observatory on the map.

You’ll learn about Clyde Tombaugh, the tenacious 23-year-old Kansanite who discovered Pluto in 1930, as well as the arduous process that led to his historic discovery. Is Pluto really not a planet? Find out on this historic tour!
