Dancing with the moon

Real Estate Broker/Owner with Robin Rogers, Silverbridge Realty, San Antonio, Texas 398351

 Full moon over Cibolo, TexasThe moon dances around the earth, completing its circle every 27.322 days.

Why can we earthlings only see one half of the moon? Over the millennia, the earth’s gravitation eventually made the moon slow its rotation around its axis. Now it matches the time that it takes to go around the earth. The dark side of the moon isn’t really dark, just invisible to us from earth.

Speaking of rotation, the moon’s energy that causes tides is slowing down earth’s rotation by a whopping 1.5 milliseconds a century.

The moon is using rotational energy to get away from the earth. It started out about 14,000 miles away when it was formed, and is now more than 280,000 miles away. And it’s making good progress: every year its orbit gets larger by about 3.8 centimeters. At that rate, it will only take, oh, 50 billion years or so before it breaks free.

Maybe after it escapes the earth's hold, the moon will find a new dance partner.

 Good morning Robin. Interesting facts. By the time the moon breaks free of Earth's gravitational forces we will all be long gone and not even be a distant memory.

Sorry, Tom, that was not my intent. You are significant! You are a child of the universe!

Michael, maybe by then the moon will have been colonized. It might even be turned into a spaceship.

I was thinking of Pink Floyd too when reading your title, and it does leave you a bit magical!

Roy, the sun finally came out this afternoon, so I will keep my camera ready.

There's nothing wrong with Pink Floyd, Elizabeth and Joan! But you have to be in the mood for it.

Hello Robin ... this is some very interesting information and VB is a "Moon Fan"

And here is some very interesting information to add to your knowledge. A friend of mine over 25 years mentioned to me that a "Truly" Full Moon only comes around every 7 years. He took classes in college on Astrology
