SAVANNAH, Ga. (Aug. 14, 2008) – The North Star is often thought to be the brightest in the night sky. Although it is relatively bright, the experts at Farmers’ Almanac say it actually ranks No. 48.
For centuries, the North Star has been used by explorers to determine latitude and chart navigational maps. Several cultures have created stories to explain why it seemingly never moves. Although the earth’s axis points to the North Star, the gravitational pull of the sun and moon causes its direction to shift slowly over time. So the North Star changes as well.
Because this happens extremely slowly, a single star typically holds the title of “North Star” for many years. Currently, the earth’s axis points to Polaris, making it today’s North Star.
