What is the altitude of polaris viewed from paris, france?

Polaris is the brightest star in the constellation Ursa Minor. Polaris is located near the north celestial pole, the point in the sky toward which the earth's north pole points. It follows that Polaris' seen elevation above the horizon of the north is about equal to the observer's north latitude. The altitude of Polaris from Paris is about 48.50. This is true for every place on the surface of the earth. 90 degrees is the highest altitude for any sky object.
