The names of the planets are in order of their distance from the sun, complete with their year of discovery (or approximate era of discovery).

Pluto's small size and unusual orbit has led to disputes over whether it can truly be considered a planet. Until further evidence suggests that it is not a planet, it shall stay on the list.

Edit: Pluto is no longer a planet. So off the list it goes.

Pluto's planet status is currently under debate, as it has for years, unofficially. So, if it gets demoted, there would be only....um, nine planets according to your list.

It looks like Pluto may well be classified as a planet, or rather a pluton, giving us, for now, twelve planets, including Ceres (the asteroid in between Mars and Jupiter), Charon (formerly believed to be Pluto's moon), and 2003 UB313 (unofficially known as Xena). I'll update the list when there's complete confirmation.

What happened to the Dr. Who planet?
Everything I thought I knew, I no longer do.

You want me to keep it now? I don't know...the episode WAS called The Tenth Planet, now it makes little/no sense without a ninth.

And then there's the matter of a list of dwarf planets that I'll have to compile...

When was planet Earth discovered?
