58. THE STARS 



Only an estimate can be made in regard to the number of 

 stars, but approximately five thousand are visible to the 

 naked eye, while probably more than one hundred million can 

 be identified with the modern astronomical instruments. We 

 must remember, too, that all the stars are suns, and that it is 

 quite likely that some suns have their planets revolving 

 around them, which are too small to be seen.
