More Pluto stuff -
Pluto is very small. I read somewhere that it was only a fifth the size of the moon. That seems tiny, perhaps I'm wrong.
In 1968 astronomers discovered Charon, a moon orbiting Pluto. Charon is about half the size of Pluto. In 2005 two other moons, Nix and Hydra, were discovered by the Hubble Space Telescope.
So what will Pluto do now that it is officially a 'dwarf planet'?
Although an appeal against the decision can't be ruled out, friends say that it will continue to orbit the sun for the foreseeable future.
A film deal with Tom Cruise (also sacked this week) is possible, but it's hard to see how an object so far away could have anything but a minor role.
Pluto's range of expression are rather limited, though that didn't stop Charles Bronson or Sylvester Stallone, of course.
Some other solar system curiosities, before we pass on -
Saturn is so light that it would float on water, but you would need a very large lake or sea to do this.
Uranus is unique among the planets of the Solar System in having a name that can sound very rude if you pronounce it a certain way. This has been the source of quite amusing jokes.
