Traditional Celebration Ideas

Today is a great day to think not only about the moon, but astrology in general. You could visit a planetarium to get some education as well as entertainment about the moon, galaxies, and the solar system.  If you have a telescope, you can invite some friends over tonight and take turns viewing the moon close up.  You could read or watch documentaries about mans first trip to the moon.


The moon has a radius of 1,079.4 miles.


In new and modern research, it has been reported that the Moon was formed 4.51 billion years ago, or maybe 100 million years earlier, 50 million years after the origin of the Solar System.  In biblical reference to the moon, specifically in the book of Genesis Chapter 1 verses 14-16, we learn,  "And God said, Let there be alights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years: And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so. And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also.  As for the composition of the moon, it is a differentiated body with a geochemical crust, mantle, and core. The Moon has a solid iron inside core with a radius about 150 miles and a fluid outer core made of liquid iron with a radius of about 190 miles. It can be best seen at night in its majestic beauty in places such as Moab, Utah where stargazing is a common hobby.
