    Default Sun's Sibling Found



    I posted this about three years ago and it was met with resounding silence. Hopefully with many new members since then, perhaps someone might find it interesting and actually seek out this star if for nothing else than simple curiosity. Anyway, below is what I originally posted in 2014, so let's see if anyone finds it interesting this time around!

    The below article indicates that they have found a very good candidate for a sibling of the Sun. This magnitude 6.55 star lies about 110 LYs away in the constellation Hercules. Its catalog designation is HD 162826 or HIP 87382. If you would like to see it for the sake of seeing it, I made the below chart to help guide you to this interesting star. Note it is the western most star of a prominent curve of three stars (5.32, 6.01, 6.55), one-third of the way along a line from Theta to Iota Herculis. Also notice that it lies about 7° southeast of the globular M92. Enjoy.

    I don't think I was a member here in 2014, so maybe I can be forgiven for overlooking this the first time round.

    I remember reading about this, but never bothered to look at the star through the telescope. Now, my curiosity is more engaged, and I'm anxious to try for it. The only problem is that Hercules is already well into the College Station skyglow by the end of twilight. I can't even make out all of the keystone stars in Hercules without using averted vision. But if I try soon enough after sunset and use my finderscope as my eyes, I think I'll be able to track it down.

    Thanks for re-posting this, Alan! Something to look for on those moonlit nights when galaxies and nebulae are out of reach.

    Wow that is nice I will have to try finding that when Hercules is higher in the sky.

    Neat. Thanks for sharing (again!).

    I wonder if it has planets too.

    Hey, thanks for the responses. I am heartened to see people take an interest (finally)!

    Yeah, unfortunately Hercules is getting to be more of a struggle by now. I only brought this up again as I was looking through files on my laptop and ran across the chart I had made and thought - man that sounds familiar. So I dug up my original post and tossed it back out there to see if anyone would notice. I will try to remember and remind folks when Hercules is more prominent again next year.

    I saw it in May 2014. It is 15% more luminous than the Sun, so it looks about as bright as the Sun would be at 100 light years.

    Thanks for the comment, and happy someone took a few moments to pursue this special star.

    Actually there were no comments on that thread. I think it was one that simply flew under the radar. But seems to have drawn a little more attention now. The star is bright enough it only needs binocular to see.
