Sometimes it just happens...

My oldest son loves the solar system. We've done the Apologia elementary astronomy book twice - once when he was seven & again when he was nine. He just takes it all in. While we were at my sister's, he created the drawing below in Paint. I have to only assume he's correct since I have no retention of the facts on how many moons each planet has. :-) (You will need to click on the photo to enlarge it enough to read. I had to shrink it to 45% of normal in order to print it out on one page.)
