Polaris, or the North Star, sits almost directly above the North Pole; therefore, it is a reliable gauge of North if you find yourself lost on a clear night without a compass. Stars that sit directly above the Earth’s North or South Pole are called Pole Stars. Interestingly, the North ...

Then the Sun subtends an angle of from the pole star (Polaris in the northern hemisphere, Sigma Octantis in the southern hemisphere), and appears to rotate around that pole star once every hours. On the other hand, if one is at a latitude , then the pole star an elevation of above ...
Pinpoint the two stars at the end of the "bowl" of the Big Dipper, draw an imaginary straight line between them, and keep following that line towards the north. The first bright star you come upon will be Polaris, at the end of the handle of the Little Dipper....

Let's say that a star is 1 million light-years away. The light from that star has traveled at the speed of light to reach our planet. Therefore, it has taken the star's light 1 million years to get to our planet, and the light we are seeing was created 1 million years ago. So...
To the north, Cassiopeia, Ursa Major ("The Big Dipper"), and Ursa Minor ("The Little Dipper") tend to be the easiest constellations to pick out. You can even use the Big Dipper to find the Little Dipper, as well as Polaris, the North Star....
