Does the Sun Have Long-Lost Siblings?

The video explores the formation of the sun and its potential solar siblings, formed in a star cluster billions of years ago. It discusses the challenges in identifying these siblings due to the dispersion of star clusters. Astronomers use chemical fingerprints to identify stars with similar origins. A team led by Ivan Ramirez identified HD 162826 as a potential solar sibling, sharing chemical and age characteristics with the sun. The video concludes with a call to support SciShow Space.

What challenges do astronomers face in finding solar siblings?

What is the name of the star identified as a potential solar sibling, and what are its characteristics?
