Clyde Tombaugh took photographs of Pluto on January 23, 1930 from Lowell Observatory in Flagstaff, Arizona. It would be a few weeks before he realized that he had discovered another planet. From 1930 to 2006, our solar system had nine planets, until Pluto was demoted to dwarf planet. The New Horizons spacecraft flew by the (dwarf) planet in July 2015, sending back googols of data.
Pluto has five moons: Charon, Nix, Hydra, Kerberos and Styx. But it is smaller than 7 moons of other planets: Ganymede, Titan, Callisto, Io, Europa, Triton and our moon.
Clyde Tombaugh was 24 when he discovered Pluto.
