Physics 105 Daily Exercise for Tuesday 10/6 (Due 10/8)

So far this semester we have considered only that Earth's axis is tilted at 23.5 degrees relative to its orbital plane (the area swept out by Earth on its orbit) and always points in the same direction relative to the stars.   This tilt allowed us to describe the motion of Sun in the sky and the seasons, etc.  It turns out that this tilt moves in a circle or precesses, like that of a spinning top, every 26,000 years.

1. What does this precession mean for the position of the North Star, Polaris, over time?
2. What can you say about how this precession affects the position of the equinoxes and solstices over time?  Specifically, in 13,000 years what would happen to the equinoxes and solstices?

Answer in the form below, a short answer for each is fine. 
This report is due by 8:00 am Thursday morning.
