Episode overview

The nearest star - not counting our own sun, which is a star - is 25 million million miles from us. Patrick Moore uses a school cricket-pitch to show how the distances of the stars have been worked out: and he explains that, because the light of stars travels so far to reach us, we see many of them not as they are now but as they were centuries ago.
