Dwarf planet Pluto's name was given by 11-year-old girl
The name of dwarf planet Pluto, which was discovered on February 18, 1930, was suggested by an 11-year-old British girl named Venetia Burney. She had suggested to her grandfather that the new discovery could be named after the Roman god of the underworld. Following this, he forwarded the name to the Lowell Observatory in the US and it was selected.
