Do you live in a big city permeated with light pollution? Never been camping? Or has just no one ever pointed it out to you?
Polaris, the North Star, is an important navigational star because its position in the sky is almost exactly (within a few degrees) lined up with the rotational axis of the Earth. This means that no matter where you are on the Earth (so long as you're in the Northern Hemisphere) if you face toward Polaris you are facing North. Finding Polaris is an incredibly useful night time navigation technique that's helped everyone from the Egyptians to the Vikings find there way on the open seas. But it also is one of the easiest stars to find - something my Dad taught us as kids - and can serve as a great entryway into the world of star gazing and constellations. In fact, locating it involves two of perhaps the three most recognizable constellations in the northern hemisphere (two of which we'll mention in a second; the third being Orion, the hunter).
Let's get started.
