"The tally of planets in our solar system would jump instantly to a dozen under a highly controversial new definition proposed by the International Astronomical Union (IAU)."So now I need to update my rhyme:
"Marsha Van Eats Mulberry Jam, Sitting Upon Neds Pony."
12 Planets:
"Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto, Charon, and the provisionally named 2003 UB313."
"Marsha Van Eats Mulberry Currant Jam, Sitting Upon Neds Pony Circa 2003." ;-)
