My atlas of bright stars says that the distances to the stars in Ursa Major are:
Star............Distance alpha 32 pc beta 24 pc gamma 25 pc delta 28 pc epsilon 25 pc zeta 27 pc eta 45 pc theta 20 pc iota 15 pc kappa 90 pc
while for Ursa Minor:
alpha 240 pc beta 32 pc gamma 83 pc
The major stars in the Big Dipper seem to be the closest to us, and to each other, at an average distance of 26 parsecs or about 85 light years.
