Although Pluto has been reclassified and no longer is called a planet, it was on this date in 1930, that Percival Lowell discovered the mysterious "Planet X." It had been suspected by this scientist for a decades, but it was finally observed on this date in an observatory in Arizona.
A survey went out requesting a name for this new planet, and it was and 11-year-old girl in England who proposed the name "Pluto." Although there was no reason behind the name, it stuck if for no other reason than it had the initials "P-L" which referred back to the scientist who discovered it.
Once my daughter began going to school, I discovered that this was no longer a planet, and that seemed so strange. When you have grown up with the idea of nine planets and now were down to eight, it just has never seemed right. And I have heard that one day, it may be reclassified yet again as a planet, and this would be even more difficult to understand. As far as I'm concerned, just call it a planet and have done with it!
