So then I was thinking, does this mean Libra constellation is only 20 light years away? Nope, because the constellations are mapped by our view of them in the sky. So I found out, for each constellation, there could be stars hundreds of light years away from each other.
Now I was ruminating on Battlestar Galactica final episode. I kinda noticed in the final pullout effect, the zoomed out of the galaxy, but kinda zoomed back in to near where they had zoomed out.
So I started looking at each constellation, and decided to check the list ( http://en.wikipedia.org/wiki/List_of..._constellation ) and come up with the *nearest star and furtherst star from Earth* for each constellation. Very geeky, I know. Well, it's Sunday, and I got nothing else to do, I'm not supposed to be working today (not a religious thing)...
The order is from right to left from http://www.dacha.freeuk.com/zodiac/dsm-b.htm . The Battlestar Galactica "colony" name is next to it. Okay, let's get into it. LY = LightYears. Any corrections of course, feel free to mention
