The easiest way to imagine the movement of the sky... Is to use an umbrella. The sky appears to rotate as the earth turns, and if you were standing directly under the true North or true South still points in the sky, it would be as you were standing holding an umbrella in the usual way, with the handle, or pole of the umbrella straight up and the umbrella above your head! But if you were at the equator? The pole star is on the horizon!  Now imagine holding the umbrella at 90 degrees to your body. The handle would point directly away from you, and the still point, if you twisted the umbrella to spin like the sky seems to, would be on the horizon. The angle of the pole to the equator is your latitude. The latitude of the North pole is 90 degrees...N And the latitude of the South pole is also 90 degrees....S And so the latitude of The Equator - that runs around the middle of the earth - is 0 degrees. So if you used a set of compass needles - the sort you use to draw circles - and ke
