Mizar
Mizar is the middle star in the "handle" of the famous Big Dipper constellation!
It was the first double star (two stars that can appear as one due to their closeness) ever recorded! The other star is Alcor.
It's about 83 light years away, so it wee see it as it was when your grandparents were born! (very rough estimate, I don't know your grandparents' age.)
It's estimated at 370 million years old, so about 1/12th the age of our Sol. (I googled it but my head math was right!) (mostly)
