Astronomically speaking, the eleventh house is that one-12th sector of the local sky midway between the Midheaven and the eastern horizon (see above picture) occupied by planets two to four hours after they rise.

The eleventh house is where we find our identity within a group; it symbolizes one-to-many relationships as distinct from Seventh house one-to-one relationships. It rules friends, groups, our social circle, membership in societies and organizations, ideals and aspirations shared by the groups to which we belong, and in general, situations in which we have to change our behavior to get along with more than one other person at the same time. Planets in the eleventh house show the kind of friends we attract to us, or the kinds of energy we experience in relation to groups. Many planets in this house indicate that we live a large part of our lives in connection with our friends or groups, and often need group support to accept or value what we are doing.
