How Far Away are the Stars?
The sun is just 93,000,000 miles (or 14,88,000,000 km) away from the earth. That seems an awful lot of distance, but light can travel so quickly that the sun's rays reach the earth in a little more than eight minutes! That is the wonder of light.
Many of the stars that we see at night, are more than 1000 times farther away than the sun. Obviously, this means that their light, too, would take 1000 times more time to reach the earth. And most stars are so far away that their light takes hundreds or even thousands of years to reach us.
The distance travelled by light in a year, is called a light year (for those who have a head for figures, one light year is 58,780,000,000,000,000 miles).
Therefore, if light takes 100 years to travel from a star to the earth, we say that the star is 100 light years away (100 x 58,780,000,000,000,000 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. One of them is Alpha Centauri, which is 4.35 light years away.
