Did you know...

That a Day on the Moon is the same as a Year on the Moon?

A day is defined as a celestial body's period of rotation around it's axis.
A year is defined as a celestial body's period of revolution around whatever it's orbiting.

The moon is in synchronous rotation - both of these periods are 27.321 days, which is why the moon always shows us the same face.

Which, of course, led to that dreary Pink Floyd album.

(There's currently a furious debate going on between our help desk manager and LHS as to how this can be so. I hope it doesn't come to blows... )

    Dreary, and of course, incorrect. There is no "dark side" of the moon, just a side which is always facing away from the Earth. It gets plenty of sunlight.

    Of course there's a dark side of the moon, it's the hemisphere farthest from he sun. But that's a stupid title for an album "The side of the moon farthest from the sun"... Sounds like a great title for an album one of you guys write... Make sure it's not _dreary_!!
