I don’t know how I could have missed this. It is unthinkable. Did you miss it too?

The passing of Pluto as a planet was bad enough, but now the girl who grew up and old, the girl most famous for naming Pluto, has also passed to the other side.

Yes, folks, Venetia Phair died on April 30, 2009, 79 years since she first thought of naming the long sought and then newly discovered planet Pluto.

Astronomers had been searching for the so-called Planet X for decades. When it was first photographed by the Lowell Observatory in Flagstaff, AZ, astronomers from around the world were electrified. They spent a great deal of time arguing over the name. Eleven year old Venetia’s grandfather, a retired Oxford librarian, wondered to his grand-daughter what it should be called. Over breakfast, Venetia asked “Why not call it Pluto?” The grandfather told an astronomer, who thought it was an excellent name; he said that the Royal Astronomical Society had spent an entire day discussing the name and did not come up with anything nearly as good. The astronomer telegraphed the Lowell Observatory (named after Percival Lowell) and they agreed it was a perfect name - it would memorialize the place it was discovered with the P-L in Pluto also standing for Percival Lowell. After much controversy in the astronomy world, the name was eventually adopted.

What is in a name?

Walt Disney, like everyone else, was captivated by the name. He named Mickey Mouse’s dog Pluto. Victoria came to be irritated by the incorrect assumption that she had named the planet after the Disney dog. No, she understood that Pluto, as a Roman god, matched the Roman god names of all the other planets. She also knew that the Roman Pluto was the elusive master of a cold, dark, hidden place.

Mythology and astronomy ran in the family. Victoria’s great uncle succeeded in naming Mars’ moons - Phobos and Deimos, fear and terror, the two companions of Mars the war god.

Venetia was alive to see her planet demoted to a planetoid. But she was also alive to see the planetoids honored with a special name - plutoids. Venetia was honored by having an asteroid and a key instrument for exploring Pluto named after her. Her naming genius was memorialized in the Periodic Table of Elements with element 94 - plutonium.

Farewell, Venetia, and thanks for a plentitude of plutoids to please us for posterity.

    It should be noted that the IAU’s controversial demotion of Pluto is very likely not the last word on the subject and in fact represents only one interpretation in an ongoing debate. Only four percent of the IAU voted on this, and most are not planetary scientists. Their decision was immediately opposed in a formal petition by hundreds of professional astronomers led by Dr. Alan Stern, Principal Investigator of NASA’s New Horizons mission to Pluto. Stern and like-minded scientists favor a broader planet definition that includes any non-self-luminous spheroidal body in orbit around a star. The spherical part is important because objects become spherical when they attain a state known as hydrostatic equilibrium, meaning they are large enough for their own gravity to pull them into a round shape. This is a characteristic of planets and not of shapeless asteroids and Kuiper Belt Objects. Pluto meets this criterion and is therefore a planet.

    Interesting - I love Pluto and happy to hear that Pluto’s plumpness may be the undoing of his undoing! THanks!

    With havin so much content do you ever run into any issues of plagorism or copyright violation? My website has a lot of completely unique content I’ve either created myself or outsourced but it looks like a lot of it is popping it up all over the web without my agreement. Do you know any techniques to help reduce content from being ripped off? I’d genuinely appreciate it.| Customs brokerage in Kenya

    I wish to show my appreciation to this writer just for bailing me out
    of such a dilemma. As a result of looking through the world-wide-web and coming across strategies which were not helpful, I thought my life was well over.
    Existing without the solutions to the difficulties you’ve sorted out by way of your entire short article is a serious case, and those that might have negatively affected my career if I had not discovered your site. Your good training and kindness in maneuvering every item was very useful. I am not sure what I would have done if I hadn’t come upon such a subject like this.
    I can at this moment relish my future. Thanks for your time so much for this high
    quality and effective guide. I won’t hesitate to refer the website to anyone who would like counselling on this area.
