The shrinking moon?

I found this via dduane on twitter.

According to the article:

The Moon is shrinking!

Well, a little: new results from the Lunar Reconnaissance Orbiter indicate that over recent geological time, the Moon has shrunk by approximately 100 meters in diameter!


Well, you have to put this into perspective: the Moon’s diameter is about 3475 kilometers. This shrinkage is only about 0.003% of that. In other words, you’d never, ever be able to see that by comparing the Moon’s diameter now as it was, say, a billion years ago.
