Scientists studying the North Star Polaris found that it is about 323 light-years from the sun and Earth, substantially closer than a previous estimate of 434 light-years by a European satellite in the late 1990s. read more

While Polaris is the North Star today, it won't always remain so. The Earth's axis actually wobbles over centuries in a pattern that astronomers call precession. In the year 14,000, this precession will aim the Earth's axis closer to the bright star Vega than Polaris. read more

Polaris is about 430 light-years away from Earth, or 4.07 * 1018 meters, or 2.53 * 1015 miles. read more
