GREAT FALLS: Those having trouble remembering the newly assigned 11 planets, including three dwarfs, can thank a fourth-grader here in Montana, United States.

Maryn Smith, the winner of the National Geographic planetary mnemonic contest, has created a handy way to remember the plants with the phrase: My Very Exciting Magic Carpet Just Sailed Under Nine Palace Elephants.

The recognised planets are Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto and Eris. Ceres, Pluto and Eris are considered dwarf planets. — AP
