The Moon was closer to the Earth yesterday (on average).
The Moon is receeding from the Earth at a rate of 4.3cm/yr.
This figure has been established by laser ranging against reflectors left on the lunar surface by the Apollo astronauts.
Every day, the Moon receeds just a little bit more...

The moon was created when a huge asteriod plummeted into the Earth. A huge chunk of Earth came out, and started to float around us. It came from Earth, and every year moves a little further away.

The Moon does NOT move away a small amount each moment, the eccentricity in its orbit allows it to move closer to us at times even though its ORBIT is expanding and moving away from us.

Hi. Yes. It moves away a small amount each moment. Maybe an inch a year. Possible causes http://groups.google.com/group/sci.astro/browse_thread/thread/f5e77fb002072bc4
