How To: Find the North Star, Polaris
In this tutorial, we learn how to find the North Star. To find this, measure the angle distances on the sky, while using your hand stretched out at arm's length. For the angles, three joined fingers make 5 degrees and a fist makes 10 degrees. You can make 15 to 20 degrees using your entire hand. Polaris is in the center of the sky, but it is not the brightest star there is. If you can find the Big Dipper, you will be able to find the North Star because it's in line with this.
