As you travel northward, the altitude of Polaris, or the North Star, increases. This is because Polaris is positioned almost directly above the North Pole, so at the North Pole, it is located directly overhead at an altitude of 90 degrees. Conversely, as you move south, the altitude of Polaris decreases.
Polaris, also known as the North Star, is particularly useful for navigation because it remains fixed in the sky while other stars appear to move throughout the night. Its location directly above the North Pole makes it a reliable reference point for determining direction, especially for travelers in the Northern Hemisphere. Additionally, its brightness and visibility make it easy to spot in clear night skies.
It is useful because it is directly above Earth's north pole so if you were traveling north, you would know what to follow
We do not yet have the ability to travel such distances.
The altitude of Polaris, also known as the North Star, is approximately equal to the observer's latitude in the Northern Hemisphere. For example, if you are at a latitude of 40 degrees north, Polaris will be about 40 degrees above the northern horizon. This relationship makes Polaris a useful navigational reference for determining one's latitude. In the Southern Hemisphere, Polaris is not visible.
The angular distance from Dubhe to Polaris is approximately 25 degrees. Dubhe is part of the Big Dipper asterism in Ursa Major, while Polaris, the North Star, is located in Ursa Minor. This distance can be useful for navigation, as it helps locate Polaris in the night sky.

To navigate using the North Star, also known as Polaris, locate it in the night sky; it is situated nearly directly above the North Pole. First, find the Big Dipper constellation, which can be used to identify Polaris: draw an imaginary line from the two stars at the end of the bowl of the Dipper to the North Star, which is approximately five times that distance. Once you've identified Polaris, you can determine true north, allowing you to orient yourself and travel in the desired direction. This method is particularly useful for travelers in the Northern Hemisphere.
