Question

From which hot spot would you view Polaris at an altitude of 45 degrees?

Answer 1

Polaris would be viewed at an altitude of 45 degrees from a latitude of 45 degrees north. The altitude of Polaris above the horizon corresponds to the observer's latitude, decreasing as one moves southward from the North Pole to the equator.

Step-by-step explanation:

You would view Polaris at an altitude of 45 degrees if you were located at a latitude of 45 degrees north. This is because the altitude of Polaris above the horizon directly corresponds to the latitude of the observer. At the Earth's North Pole, Polaris is directly overhead (at the zenith) at 90 degrees. As you move southward to the equator, the altitude of Polaris above the northern horizon decreases accordingly. At the equator, Polaris lies on the horizon, which is 0 degrees altitude. Therefore, to see Polaris at a 45-degree altitude, you must be halfway between the equator and the North Pole—that is, at the 45 degrees north latitude.

The altitude of the north celestial pole (close to Polaris) in the sky for someone located at the same latitude remains constant regardless of the Earth's rotation. If someone moved southward from their location, the altitude of Polaris would decrease, as it appears lower in the sky the closer one gets to the equatorial region.

Answer 2

Massena, New York

Step-by-step explanation:

Polaris is most popularly known as the North star. It is also famous by the name of "Pole Star". It is the closet to the north celestial pole. At present it is the northern pole star currently.

It is found in the constellation of Ursa Minor. It is the one of the brightest star seen in the night sky. It is considered the star of the second magnitude which is situated close to the heaven's north pole.

The altitude of the Pole star or the Polaris when an observer is at the Tropic of Cancer is measured at 23.5 degree. While if the observer sees the Pole star at its zenith, the observer is located at the North Pole. i.e. 90 degree.

And the spot from where the observer views the Polaris at 45 degree altitude is Massena, New York.
