Clyde Tombaugh announced his finding of a tiny bright dot that moved, proving that it was a celestial body circling our sun and not just another star. Halfway around the world in England, 11-year-old
Venetia Burney suggested that the new planet be named “Pluto,” for the Roman God of the Underworld who could make himself invisible. On 1 May 1930 the name “Pluto” was formally adopted for this new celestial body.
