What is the movement of polaris with change of latitude?

Polaris' 'elevation' ... the angle between it and your northern horizon ... is roughly equal to your

north latitude.

When you are . . .

. . . on the equator (zero latitude), Polaris is on your horizon;

. . . in Salem Oregon, Minneapolis, Grenoble France, Torino Italy, Ploiesti Romania, Jixi China,

Wakkania Japan, etc. (45 degrees north latitude), Polaris is 45 degrees above your northern horizon;

. . . at the north pole (90 degrees north latitude), Polaris is directly overhead;

. . . south of the equator, Polaris is due north of you but below the horizon.
