New Science Snippet from Texas Author

For everybody's edification here's a science snippet:

Why is a total solar eclipse possible?

This is a bit of a tricky one and has to do with the relative sizes of the moon and the sun as seen from the earth. The sun appears to be the same size as the moon and is therefore able to completely block out the sun. If the moon were to be larger or smaller we wouldn't have the spectacular eclipses that we have. It turns out that both the sun and moon are about a 110 times their diameter away from the earth. Any round object that is 110 times away from the observer will appear to be the same size as the moon or the sun.

I'm a neophyte in doing this but if anybody needs an independent review of a work--preferably science or science fiction, or at least related to science or science fiction, I'll be glad to look at it. I have an extensive physical science background and have worked in many different areas of science. I'm currently writing science based study guides and science fiction novels. I have also published two books for young readers with a modicum of science in each of them. You have my permission to review them both. If you do I'd appreciate your sending me your review. The books are "Astronaut Training" and "A Visit to the Farm." Have a good day.
