Itokawa: a Sub-km, S-type, Rubble Pile Asteroid Investigated by Hayabusa

Thermal infrared observations of the Hayabusa spacecraft target asteroid 25143 Itokawa ⋆

We obtained N-and Q-band observations of the Apollo-type asteroid 25143 Itokawa during its close Earth approach in July 2004 with TIMMI2 at the ESO 3.6 m telescope. Our photometric measurement, in combination with already published data, allowed us to derive a radiometric effective diameter of 0.32±0.03 km and an albedo of 0.19 +0.11 −0.03 through a thermophysical model. This effective diameter...
