Polaris is approximately 430 light years from the Sun.
Owing to its fortuitous position aligned with the north pole of the Earth, Polaris is commonly used for navigation; a sextant reading of Polaris can, with a very minor correction, be read as the latitude of a ship. However, Polaris is not especially bright; in fact, it is the dimmest star commonly used for celestial navigation.
Each light year is about 9.5 x 1012 kilometers or 5.88 × 1012 miles

No. Polaris is a star (actually a system of 3 stars), far too hot for water to exist. There is no known evidence of planets in the Polaris system.
The main star in the Polaris system is 20.6 to 26.9 million AU away.

Please identify which sun.
Polaris is about 430 light-years away from Earth, or 4.07 * 1018 meters, or 2.53 * 1015 miles.
No, Rigel is not the closest star to Polaris (the North Star). Rigel is a bright star in the constellation Orion, while Polaris is located in the constellation Ursa Minor. The closest star to Polaris is Urodelus, also known as "Polaris Australis."
Polaris by far. It has a diameter of 75 times the diameter of the Sun. Alpha Cen B has a diameter of 1.7 solar diameters.
There are a couple of reasons that make Polaris, the north star, very useful. First of all, Polaris is not DIRECTLY above the North Pole; it's about two thirds of a degree off. But that's close enough so that if we assume that Polaris is exactly above the North Pole, you won't go very far off. So if you can see Polaris, you know which direction is north. If you measure the elevation angle above the horizon of Polaris, your reading is your latitude. No calculation is necessary!
4,096,409,000,000,000,000 metres (4.096409 x 1018 metres) or 433 light years.
Distances to stars are not measured in kilometres, but since you have asked, Polaris is 3-4 quadrillion kilometres away.
