If you go out to look at the night sky tonight from central Iowa, the North Star (aka Polaris) is located near the North Celestial Pole at an altitude of approximately 42 degrees above the horizon. Why is that the case? What is the altitude of the celestial equator at its highest point as viewed from this location and how do we calculate that?  Explain the myth behind one of the constellations located near North Celestial Pole and then explain the myth behind another constellation along the ecliptic plane.
Is there any place on Earth where all the visible stars are circumpolar? If so, where? Is there any place on Earth where none of the visible stars is circumpolar? If so, where? Explain your answers.
Description: If you could see both the Sun and the other stars during the day, this is what the sky would look like looking south at noon on January 1 for an observer in the northern hemisphere. The Sun would appear in the sky next to the more distant stars in the constellation Sagittarius, (labeled constellation C). Also shown are other constellations (named and labeled A, B, D, and E) that will be visible above the horizon at this time when facing south.
