Question
Enter your estimated angular distances between the following stars. Round your answers to the nearest degree. 1. the angular distance between "pointer stars" Dubhe and Merak is about 2. the angular distance between Merak and Phecda is about 3. the angular distance between Dubhe and Megrez is about 4. the angular distance between Megrez and Alioth is about 5. the angular distance between Alioth and Alcor/Mizar (a double system) is about 6. the angular distance between Alcor/Mizar and Alkaid is about 7. the angular distance between Kochab and Polaris is about 8. the angular distance between Kochab and Pherkad is about 9. the angular distance between Dubhe and Polaris is about degrees degrees. degrees degrees. degrees degrees. degrees degrees. degrees.Explanation / Answer
You know what to use and the distances you can measure in the sky using your own hands, try to calculate the distances within the stars in the Big Dipper. You´ll see that the Big Dipper measures approximately 25° from Alkaid to Merak and that the angular distance from Phecda to Merak is of approximately 8°.
With your fist, you could easily measure the distance-10.3°, from Megrez to Dubhe, which is the top of the bowl and using three fingers, you may obtain the angular distances that separate the rest of the stars within this conspicuous asterism.
To easily spot the Big Dipper on any given night, try to choose a place away from any city's light pollution or use the shadow of a building or a tree to block any ambient light.
Since the Big Dipper is a circumpolar asterism (never sets below the horizon), people living in the northern latitudes of the world would be able to observe it more above in the sky and for longer periods of time than those living in the southern latitudes.

The altitude of the North Star is about
At the Equator (0° of latitude), the North Star is on the horizon, making an angle of 0°. For any point between the Equator and the North Pole, latitude is obtained simply by measuring the altitude of Polaris: at 30°N the star is 30° above the horizon, at 63°N, it is 63° above the horizon, and so on.
