In September 2011, the Herschel Space Observatory performe d an observation campaign with the PACS photometer observin g the asteroid (101955) 1999 RQ 36 in the far infrared. The Herschel observations were analyse d, together with ESO VLT-VISIR and Spitzer-IRS data, by means of a thermophysical model in orde r to derive the physical properties of 1999 RQ 36. We find the asteroid has an e ffective diameter in the range 480 to 511 m, a slightly elongate d shape with a semi-major axis ratio of a… Expand
