Downsizing Hits Everywhere

It’s official. Pluto is no longer considered a planet.

Pluto had a long run as a planet. It was discovered by Clyde W. Tombaugh on February 18, 1930.

The reason for Pluto’s demotion is that both it and its moon, Charon, are:

part of a sea of other objects that occupy the same region of space. Earth and the other eight large planets have, on the other hand, cleared broad swaths of space of any other large objects.

Less than five percent of the world’s astronomers voted on Pluto’s redefinition, so maybe it won’t stick. Meanwhile, I guess the mnemonic I learned for the planets can still be used. Mary’s violet eyes make John stay up nights… Yep, it’s still good. I just have to keep up on the news so I make sure the other eight planets still count before I teach it to the grandkids!
