Can we find the Sun’s relatives? Yes. By identifying stellar relatives via their proper motion, or apparent movement across our line of sight, their position in the sky, and their chemical signatures, which he likens to their stellar DNA. Such stars, would be roughly one solar mass (the size of the sun) or less and have chemical abundances similar to the sun.
I shot this not too long ago of the M13 star cluster.
From where I am located, it was not visible to the unaided eye.
M-13 is a Globular star cluster in the Constellation Hercules. It contains several hundred thousand stars, and is approximately 25,000 light years from earth.
It's estimated the cluster has about half million stars and is about 100 light years diameter.
It's believed the age of M13 is about 14 billion years.
That is a very good photograph.
Thanks...BTW, very interesting article you posted here.
Yes, THANK YOU for posting this thread. Interesting topic and thought provoking.
(Thanks to Sunken Civ for his comment reminding me of the value of saying THANK YOU)
I had never considered , before, the idea that our Sun had siblings.
We are all made from star stuff. The atoms in our body came from a heart of a star that blew itself up billions of years ago.
We have seen the lost siblings of the sun, and they is us.
The chemical fingerprint of those sibling systems should be similar to our solar system and if evolution started from scratch here, it may have started from scratch in those systems as well. If things must be just so for life to get started, sibling systems will be a juicy target for any ET search, if we can identify them.
Interesting fact: Alpha Centauri A and B are about the same size and age as the Sun. Could they be siblings? Maybe. I think the composition is similar. I don't know how well their motion tracks ours.
Alpha Centauri A and B could be from the same stellar nursery. If Proxima was bound to the Alpha Centauri system during its formation, the stars would be likely to share the same elemental composition. We can say its a “captured” heavenly body.
