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.
1. How does Earth's revolution affect the constellations that you see at night?
2. What is the celestial sphere?
3. What is an ecliptic? why is it given that name?
The Sun’s actual diameter is about 1,400,000 kilometers. How many “Earth diameters” is this? Given your 3-inch Earth, how large (i.e what diameter) of a ball would you need to represent the Sun?
The average Earth–Sun distance is about 149,600,000 km. To represent this distance to scale, how far away would you have to place your 3-inch Earth from your Sun?
