Group Activity (See related pages) The second star from the end of the handle of the Big Dipper is actually a double star. The two stars, Alcor and Mizar, appear double to the naked eye only for people with excellent vision. Working with your group, identify Alcor and Mizar. See if anyone in your group can see two stars rather than one. Use a pair of binoculars to let everyone see that there are really two stars.
