(a)
The sketch showing how Polaris, the Little Dipper and the Big Dipper would appear at
Explanation of Solution
Introduction:
It is known that the Earth rotates from West to East. One complete rotation around its axis is completed by Earth in
Earth rotates by
The time difference between
Therefore, the angle covered by the Earth around its axis within this time period of
Thus, at
The following figure shows the sketch showing how Polaris, the Little Dipper and the Big Dipper would appear at
Figure (1)
Conclusion:
Therefore, Figure (1) shows the sketch of how the Polaris, the Little Dipper and the Big Dipper would appear at

- Look at Figure 2-9, shown here. If you see Sagittarius high in your night sky on June 20 and today is your birthday, what is your zodiac constellation?arrow_forwardIs the ecliptic the same thing as the celestial equator? Explain.arrow_forwardLook at the view from Earth on March 1 in Figure 2-9, shown here. Is the view from Earths nighttime side or daytime side? How do you know? Which asterism or constellation is shown in this image?arrow_forward
- Suppose you are on a strange planet and observe, at night, that the stars do not rise and set, but circle parallel to the horizon. Next, you walk in a constant direction for 8000 miles, and at your new location on the planet, you find that all stars rise straight up in the east and set straight down in the west, perpendicular to the horizon. How could you determine the circumference of the planet without any further observations? What is the circumference, in miles, of the planet?arrow_forwardIs 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.arrow_forwardIf 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.arrow_forward
