The IAU faced a bit of a conundrum in 2005 with the discovery of Eris, a trans-Neptunian object larger than Pluto. In 2006 they created a new category of solar objects calling them Dwarf Planets.-The IAU recognizes the following as Dwarf Planets:Ceres, Pluto, Haumea, Makemake, and Eris-Some scientists feel that any object with a diameter greater than 900 km should be considered a dwarf planet. This would include:Orcus, 2002 MS4, Salacia, Quaoar, 2007 OR10, and Sedna.-This is an ongoing debate and is by no means settled.But if Pluto was still a planet then our solar system would have 13 or maybe 19 planets.And what a headache it woiuld be to come up with a new rhyming scheme for “My Very Educated Mother Just Served Us Nine Pizzas”-Anyone want to try for MercuryVenusEarthMarsCeresJupiterSaturnUranusNeptuneOrcusPluto2002 MS4SalaciaHaumeaQuaoarMakemake2007 OR10ErisSedna

Is Too!Planet means wanderer, it wanders, ergo it’s a planet.

Sorry Carmen, but Winslow is right on this one.

Holst’s big hit would require all night for the philharmoniacs.

Holst was apparently prescient in not including Pluto, but I do miss it, with all due respect to Neil deGrasse Tyson….
