Is Sedna the new 9th planet? I thought it was supposed to have been named "Nemesis". That was the name given to whatever has been dropping Dino killers every zillion years or so. Granted, that was the popular name in science fiction circles about 30 years ago.

There is no ninth planet since Pluto was stripped of its title and downgraded to junior varsity.
Needless to say, without Planet IX, Dr Emilio Lizardo is very frustrated.
