3\10 An orb by any other name-
 Debate over what constitutes a planet is far from settled
Part 3 of 3

What's in a name? Help us remember
----------------------------------
For ages, teachers have been creating mnemonics to help students 
remember the order of the planets. One well- known version is "My Very 
Educated Mother Just Sent Us Nine Pizzas." Another variant, mentioned 
in Robert Heinlein's book "Have Space Suit, Will Travel," goes:
"Mother very thoughtfully made a jam sandwich under no protest." 
(Thoughtfully stands for Terra, Earth's other name.) But with another 
five (or more) potential planets, it's back to the drawing board. 
Please send us your mnemonics (rls{at}pa.urel.berkeley.edu) for the 
latest solar system lineup: Mercury, Venus, Earth (or Terra), Mars,
Vesta, Ceres, Pallas, Jupiter, Saturn, Uranus, Neptune, Pluto, Quaoar 
and Varuna. The best submissions will be featured in a future issue of 
the NewsCenter, http://newscenter.berkeley.edu
