 * Polaris appears to be motionless at the center of the stars. All the other stars appear to circle around Polaris. In the early 320 B.C. the Greeks had realized that Polaris did not mark the pole exactly. Until then many people had believed that the heavenly pole was absolutely and eternally fixed. Not so. Polaris has long been moving nearer the North Celestial Pole, as it is still doing now. It will be get to that position around A.D. 2105--27'. Currently it is about 1° from the celestial pole.**

__THE POLARIS IS THE BRIGHTESS STAR!!!!!([|www.google.com])__


 * The star pulsates causing it to change its brightness by a few percent over a course of different days.Polaris is classified as the "F" star. one of the brightest stars. Polaris goes through a four day cycle of swelling and contraction from its mass.Tha then takes charge of it's luminosity. Due to that, we can find out the stars absolute magnitude and it's distance. It's absolute magnitude is -3.50 and it's apparent magnitude is +2.11 which then give us a distace of approximatly 431 lightyears.**
 * Polaris gets it's name from the latin, Stella polaris,which means "pole star".
