Got my friends' first baby her own star, awww...
Aww. Is it insured against precession? http://en.wikipedia.org/wiki/Precession_(astronomy)
Your statement is the very definition to "Esoteric". Perhaps an explanation for our studio audience?
The best way to explain this is the analogy of a spinning toy top.
Basically, we have the image that the Earth spins like a top with a stable axis as it rotates around the Sun.
Think of a top that has just been set in motion - initially it stays upright, balanced on a single point at the bottom. However, as the top slows down, it begins to wobble, tilt one way, then the other( to our eyes), till it finally falls down on one side.
What this means is that the top's 'top' initially points straight upwards, but then begins to point one way( say left), then towards you, then right, then away from you, and so on, till it stops.
The Earth is in a somewhat similar position. It 'wobbles' in its rotation, but extreeeemely slowly. In other words, if you were watching our solar system from a large distance, and you were looking at our Earth, you would see the same thing. The Earth's North Pole would point 'left', then towards you, then 'right', and then 'away from you'. The difference is that for this whole thing to occur, it takes 26,000 years. Obviously, not important in our lifetime.
So how does this relate to the stars? Simply that right now, our North Pole points roughly in the direction of Polaris( the North Star). As our Earth wobbles, however, ever so slowly, the stars 'shift' because the Earth is tilting away from them. So, say, 13,000 years from now, Polaris will no longer be the North Star! The Greek sailors, for example, used a different North Star in their navigation.
After 26,000 years, Polaris will once again be the North Star. And so on and on.
This visualization might help.

Which is why poor Joanna must be careful naming the star she wants to name, or she might find that her 1300th generation may no longer be able to see Joanna Star in all its glory.
"Mommy, where is the Joanna Star that greatgranddad says was dedicated to that really really old lady?"
