Polaris, also known as the north star, is arguably the most important star in the northern hemisphere. It has played crucial roles in navigation and aiding lost individuals, it is the location (not exactly on, but really close) of the north celestial pole used by astronomers for polar alignment.
This star can be found at the bottom of the "handle" in Ursa Minor or the "little dipper". What makes this star so special is that it has next to no apparent movement in our sky.
This area is surrounded by a vast web of IFN or "Integrated Flux Nebula". IFN are a Nebula type that are on the outer edges of our galaxy. These faint objects reflect light back from the entirety of the Milkyway galaxy.
