The childhood way of remembering the order of the planets will need to be rethought. Pluto has been officially ruled not a planet.
New definition of a planet:
"a celestial body that is in orbit around the sun, has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a ... nearly round shape, and has cleared the neighborhood around its orbit."
According to the Associated Press news article, Pluto is disqualified because its oblong orbit overlaps with Neptune's.
Pluto will now fall under a new category as a "dwarf planet."
So, can you come up with a new phrase for these letters?
