The PTF Orion project is a part of the Palomar Transient Factory (PTF), a survey for astronomical transients being undertaken with a dedicated wide-field CCD array installed on the Palomar 48" telescope. The Orion project is an experiment that during its first year is focusing on a single pointing in the Orion star-forming region. The project has been assigned 40 consecutive nights per year for three years -- the first 40 nights of which are now complete -- to perform intensive time-series observations with the aim of detecting close-in, Jupiter-sized planets transiting young stars. Little is known about the distribution and frequency of planets around stars that are 1-100 Myr old -- the time frame in which the giant planets are expected to form. Our principal goal is to investigate the frequency of planets around stars at young ages. In addition, the observations will provide a unique data set to study a variety of stellar astrophysics, including eclipsing binary systems for testing star formation and evolution models; characterising stellar activity and rotational periods; and characterising previously unknown young stars in the Orion region. Here we present early results from the first year's data set.
