[edit] Guide Star Catalog
I suspect this topic should mention the Hubble Guide Star Catalog, but I don't know enough about it to place it correctly. JTN 17:13, 2004 Sep 13 (UTC)

Teegarden's star is designated SO025300.5+165258. Which catalog is called "SO"? Icek 12:51, 29 December 2006 (UTC)
[edit] Bet you find this Interesting?
I had a thought the other day. And tried to find this answer to this on Wikipedia and other sources. But as a complete layman became very confused, parsecs/light years ect. This is my thought, we (the human race) have been sending out RF signals of a reasonable strength since 1922, please correct me on this if I have this wrong. Based on this knowledge, I wondered how far and how many star like suns (G class stars) have these RF signals reached by this year, 2007 ? You know where I'm going with this thought, and yes maybe life is not restricted to G class stars, or maybe it is, or maybe only to G2V, and we all known G2V's are capable! Then there's the age of these stars, and then the metallic make up as well. I wish someone with the right knowledge would draw up a list of theses stars. And using the above knowledge. We could then break the list up into the most lightly to the most unlikely places that intelligent life may exist. And that have also received RF signals from us. I believe this list would be helpful to SETI, to reduce their listing down to size, so they can focus on a more broader range of RF signals. As I also believe the RF's they are searching are far too narrow, and I feel a lot of time and money is going to waist at SETI. If anyone can help me with this please do, maybe I've got this wrong as I'm just a layman. But in any case, post me something, its bugging me! -- 86.10.204.128
- The Nearby Stars Database finds 191 G-type stars within 25 parsecs. That's about a parsec less than you want, but it's a start. --Zundark 09:50, 21 March 2007 (UTC)
