Recently, the Vice President of India said Parliament is the “North Star” of democracy.
About North Star:
- The North Star is also known as Pole Star.
- It is a very bright star — around 2,500 times more luminous than the Sun.
- It is part of the constellation Ursa Minor and is around 323 light years away from the Earth.
- The Northstar is less than 1° away from the north celestial pole, almost in direct line with the Earth’s rotational axis.
- It appears to sit motionless in the northern sky, with all the other stars appearing to rotate around it.
- Its position and brightness have allowed humans to use it for navigation since late antiquity.
- The elevation of the star above the horizon gives the approximate latitude of the observer.
- Upon crossing the equator to the south, however, the North Star is lost over the horizon and hence stops being a useful navigational aid.
What is Ursa Minor?
- It is one of the 48 constellations identified by the Greek astronomer Ptolemy in the second century.
- It is also called the Little Bear.
