When I was young, I had a major interest in astronomy (no, not astrology; astronomy). As I studied it, I came to be convinced that Pluto was not really a planet.
Well, it's now official. Today they decided that Pluto is what is called a "dwarf planet." They demoted it for the very reason I said: namely, that its orbit is oblong and sometimes crosses paths with Neptune. (From 1979-1999 Neptune was the outermost planet because of Pluto's strange pattern of orbit.)
I remember telling my college astronomy teacher my theory. He didn't think I was a weirdo, but he certainly didn't believe me either.
I wonder if he remembers me now?
