As of July, 2008, over 300 extrasolar planets have been discovered. The characteristics exhibited by these exoplanets provide us with details that expand our knowledge of planets beyond what we understand of the bodies in our Solar System. Through our observations of these exoplanets, we can deduce information about the angular momentum of the planet, the parent star, and the total system. This research investigates the angular momentum of the bodies in extrasolar planetary systems in hopes of finding a trend within the angular momentum held by the exoplanets. Such a trend was found on a plot of the log of angular momentum per unit mass versus the log of the mass of the star in solar masses. However, further examination is needed to describe what information this trend is bestowing upon astronomers. Additional understanding on this subject will provide a better grasp on the formation and system dynamics of exoplanets and extrasolar planetary systems. Funding for this research was provided by a partnership between the National Science Foundation, Research Experience for Undergraduates, and the Department of Defense ASSURE programs.
