    Star with great speed rush in space, but we do not notice their movements, as the star away from us at great distances. For centuries, astronomers have tried to find out how far away the stars, and could not do it. In , the director of the Pulkovo Observatory, which is near Leningrad, Struve was able to determine the distance from the star.

    The star, harbored in a very distant spiral galaxy, is so far away that its light has taken 9 billion years to reach Earth. It appears to us as it did when the universe was about 30 percent of its current age. Author: Karl Hille.

    So, how bright a star appears in the night sky depends on its size as well as how far away from us it is. The closest star is about 25,,,, miles (39,,,, kilometers) away, while the farthest stars are billions of times farther than that. Continue the conversation on.

    Therefore, if light takes years to travel from a star to the earth, we say that the star is light years away ( x 58,,,,, miles.) Some of the stars we can see in the night sky are so far away that it takes thousands and thousands of years for their light to reach us. Scientists have only been able to see some nearby stars.

    The two main stars are Alpha Centauri A and Alpha Centauri B, which are approximately light years away from Earth. The third star in the Alpha Centauri system, Proxima Centauri, is actually the closest star to our solar system at approximately ​lightyears away from Earth. Created by Sal Khan.
