Today is Pluto's big day
and, of course, it's a planet.
and it orbits a sun.
In fact, it has more right, in my book, to be called a planet than the gas giants as it is solid and I think "planet" is a solid sort of word.
You could land on Pluto and if you did you might be lucky and catch sight of one of the polar bears which, when I was a young boy, I fervently believed lived on its surface.
