WASP-12b is one of the largets planets yet discovered, with an inflated radius of 1.79 Rjup. It also lies in very close proximity to its G-type star, with a semi-major axis of 0.0229 AU and orbital period of only 1.09 days. It is one of the hottest exoplanets discovered to date as well, with an equilibrium temperature of 2516 K for zero albedo and uniform redistribution of incident flux. We observed four secondary eclipses of the WASP-12b using Spitzer's Infrared Array Camera (IRAC), which yielded six separate eclipse lightcurves over the IRAC wavelengths (2x3.6, 2x4.5, 5.8, and 8.0 μm). From these observations, we are able to constrain the planet's orbital and atmospheric properties, such as eccentricity, atmospheric composition, and thermal structure. The secondary eclipse photometry is presented along with our analysis. Spitzer is operated by the Jet Propulsion Laboratory, California Institute of Technology, under a contract with NASA, which provided support for this work.
