A pole star is a visible star that is approximately aligned with the axis of rotation of an astronomical body; that is, a star whose apparent position is close to one of the celestial poles. On Earth , a pole star would lie directly overhead when viewed from the North or the South Pole .
Tekhelet colored Star of David, as depicted on the flag of Israel. The Star of David (Hebrew: מָגֵן דָּוִד, romanized: Magen David, lit. 'Shield of David') [a] is a symbol generally recognized as representing both Jewish identity and Judaism. [1] Its shape is that of a hexagram: the compound of two equilateral triangles.
It is designated α Ursae Minoris (Latinized to Alpha Ursae Minoris) and is commonly called the North Star or Pole Star. With an apparent magnitude that fluctuates around 1.98, [ 3 ] it is the brightest star in the constellation and is readily visible to the naked eye at night. [ 15 ]
The star Polaris, often called either the "Pole Star" or the "North Star", is treated specially due to its proximity to the north celestial pole. When navigating in the Northern Hemisphere , a simple and quick technique can be used with Polaris to determine the observers latitude or, for larger maritime vessels can be used to calculate any ...
Polaris (within 1° of the pole) is the nearly stationary bright star just to the right of center in this star trail photo. The north celestial pole currently is within one degree of the bright star Polaris (named from the Latin stella polaris, meaning "pole star").

The Indestructibles (Ancient Egyptian: j.ḫmw-sk – literally "the ones not knowing destruction" [1] [2]) was the name given by ancient Egyptian astronomers to two bright stars which, at that time, could always be seen circling the North Pole. [3]
It is recognized as a distinct grouping in many cultures. The North Star , the current northern pole star and the tip of the handle of the Little Dipper (Little Bear), can be located by extending an imaginary line through the front two stars of the asterism, Merak (β) and Dubhe (α). This makes it useful in celestial navigation.
