Venetia Phair – the last person to be said to have named a planet – died two weeks ago at the age of 90. She thought up the name Pluto for the newly discovered planet in 1930 at the age of 11, and suggested it to her uncle over breakfast. He – luckily – was a good friend of the professor of astronomy at Oxford, and the name was adopted a couple of months after its discovery.
Sadly, Pluto’s classification as a planet was changed in 2006 when the definition of a planet was changed; it is now considered a dwarf planet, along with Ceres, Eris, Haumea and the delightfully named Makemake.
Interestingly, the word ‘plutoed‘ (meaning to demote or devalue something or someone) was chosen by the American Dialect Society as word of the year in 2006.
