Commonly North Star, Northern Star or Pole Star, is the brightest star in the constellation Ursa Minor. It is very close to the north celestial pole, making it the current northern pole star. Learn more on Wikipedia.

Perigees

The point in an object's orbit when it is the closest to the Earth. Super moons or moon perigees are particularly useful in photography.  Full moons that occur on the perigee side of the moon's orbit seem extra big and bright. The best time to look is when the moon is near the horizon.  For reasons not fully understood by astronomers or psychologists, low-hanging moons look unnaturally large when they beam through trees, buildings and other foreground objects. Learn more on Wikipedia.
