Astronomically speaking, the tenth house is that one-12th sector of the local sky counter-clockwise from the Midheaven (see above picture) occupied by planets two hours before they culminate, or reach the tenth house cusp.

The tenth house represents our ability (or lack thereof) to establish ourselves in and contribute to the outside world: our social image. It rules role models, guides and authority figures that have assisted us in exteriorizing ourselves in the world. Here is our career or profession, the dominant parent who guided us into the world, and our orientation toward society based on his or her example. Here are people in power over us (such as bosses and employers), our honor and reputation, and how we play out these roles in relation to others (our being a father, guide, or disciplinary figure). Planets in the tenth house show by the houses they rule which areas in our life depend on our reputation or professional role for the fulfillment of their needs. Many planets here indicate a need to achieve and be recognized as an important person, a strong father orientation, or to have others dependent on us.
