Light Years
... Distances in space are so large that it does not make sense to use a typical unit such as kilometers or miles. Instead, astronomers use a special unit called a light year to measure the distances between stars and galaxies. A light year is the distance that light travels in one year. Moving 300,000 ...

We can then determine how far away the galaxy is by observing the brightness of the stars. Such stars can help us measure the distance to galaxies 300 million light years away. If a g ...
