We propose to re-observe Apophis after opposition with very differentsurface temperatures to complete our thermophysical model study interms of sense of rotation, thermal inertia and constraints on its interior.

Mission Description
Herschel was launched on 14 May 2009! It is the fourth cornerstone mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities.
