The side effect of one proposed redefinition would be that other objects, such as the asteroidal dwarf planet Ceres and the trans-Neptunian objects Charon (Pluto's "moon" - or one half of the Pluto-Charon double dwarf planet), Makemake and Eris would also become planets, giving us 13 (thus far), and then the blogger Stephen Battersby oh so casually solicited mnemonics for the set of the 13 - and I succumbed, as I have done in the past... (c.f. Googlewhacking which wasted days of... days)
So here they are:
First attempt: nothing special , but a musical theme.
My Violin Exudes Music - Concertos Jostle Sonatas Unborn - Never Played - Charming Melodies EffortlesslySecond attempt: preserves the first two letters of each "planet" name in the mnemonic to help remember which is which (helpful if you are confused by the thought that Eris - the goddess of Discord - would be a better name for the 3rd Rock from the Sun).
