Rigel is a supergiant star that is so bright it lights up the Witch Head Nebula which is about forty astronomical units away. An Astronomical unit is the distance from the Sun to the Earth, 149,597,870,700 kilometers. Quite far.
In the Star Trek movies Rigel is mentioned quite often and is also mentioned in Douglas Adam"s Hitchhikers guide to the galaxy and there are all those computer games and comics.
I'm not sure just how much information there is on Rigel, quite a lot I would imagine but for me today, time's up and off to work I go. So with that let me bid you farewell, live long and prosper. Geoff signing out.
