Pluto

Recognizing with a bit of sadness the tenth anniversary of the demotion of Pluto from planet to ‘dwarf’ planet. 

Thanks, Neil deGrasse Tyson! 

Hardly seems fair; Pluto was just discovered in 1930, and the little fella didn’t even get one full lap as a planet before the naysayers got him. Of course, that would have taken until 2178, but what's the damn hurry?
