What is the approximate distance from Earth to the North Star?
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. The new distance measurement may help astronomers in the pursuit of several cosmic mysteries, such as the hunt for elusive dark energy, researchers said.
What are some interesting facts about the North Star?
The North Star is prominently close (about two thirds of a degree) to the north celestial pole which is directly overhead of the viewer at the North Pole on Earth.
