How far are the stars in the Big Dipper from Earth?
The stars of the Big Dipper are far enough away that the time it takes for light to reach us from them is about the time-scale of a single human lifetime. Megrez is 58 light-years away. Mizar, Merak, Alioth and Phecda are each about 80 light-years away. Alkaid and Dubhe are just over 100 light-years away.
