Did you know that Pluto may not actually be a planet? With the discovery of UB313 (See Picture!), Pluto's planethood has become dubious. The elderly astronomer who showed me the sky in Hobart, Tasmania, when I was 9 years old told me he had discovered Vulcan, the tenth planet. I was quite excited, last night, to meet UB313 at Bens' astronomy evening ... perhaps Vulcan is real!
