Image 1 & 2 Caption: A protest in the Pluto de-planet controversy: "Pluto ♇ is more of a planet than Uranus ↑☉,♅ will ever be!!!"
Alas, Pluto ♇!
There is this thing Eris (which is a dwarf planet under the new Rules of the Game (1939 film) and was discovered in 2005) which is comparable in size to Pluto and more massive.
The pesky trans-Neptunian object (TNO) Eris caused a whole nomenclature cataclysm from which we are still recovering and resulted in the degradation of Pluto to dwarf planet-dom in 2006 (see Wikipedia: Pluto: IAU classification).
Once Pluto was the NINTH PLANET, now it is an ex-planet.
Once children used to recite the mnemonic "Man very early made jars stand up nearly perpendicularly."---but now no more.
Pluto still has a faded glory.
