I'm certainly no expert on the stars, but
even my Greatkid's 5th grade science book
explains that Polaris only holds the
North Star position for approximately
14,000 years. Then its significance as
the Pole Star is replaced by Vega,
a star some distance away from Polaris'
"seeming" position. These two stars
alternate in the great scheme of things.
Guess even Science has to adjust to our
changing universe and reconsider its
findings every few centuries.
I learn something new on here every day. Thanks.
Of course, it's the pointing direction of the earth's axis which is changing. The stars themselves are staying where they are :-) I am sure *you* knew that but just in case we have any lurkers from DU...
