Group - Planetary mnemonic

A planetary mnemonic is a phrase used to remember the planets (and sometimes dwarf planets) of the Solar System with the order of the words corresponding to the increasing sidereal periods of the bodies. The traditional English-language mnemonic for many years was My Very Earnest Mother Just Served Us Nine Pizzas (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto). But, some people like to use "My Very Educated Mother Just Showed Us Nine Planets" (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto). Another mnemonic was My Very Easy Method Just Speeds Up Naming Planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune a Pluto). However, MVEMJSUNP was made obsolete by the 2006 definition of planet, which reclassified Pluto (and Ceres) as a dwarf planet. The International Astronomical Union suggested a revised mnemonic, My Very Educated Mother Just Served Us Nachos, for the eight planets recognized under the new definition. The National Geographic Society sponsored a contest for a new mnemonic of MVEMCJSUNPE, incorporating the then eleven known planets and dwarf planets, including Eris. On February 22, 2008, My Very Exciting Magic Carpet Just Sailed Under Nine Palace Elephants, coined by 10-year-old Maryn Smith of Great Falls, Montana, was announced as the winner. The phrase was featured in the song 11 Planets by Grammy-nominated singer and songwriter Lisa Loeb and in the book 11 Planets: A New View of the Solar System by David Aguilar (ISBN 978-1426302367). Since the National Geographic competition, two additional bodies have been designated as dwarf planets, Makemake and Haumea, on July 11 and September 17, 2008 respectively.
