Mid-infrared observations of the Apollo-type asteroid 162173 1999 JU3 were performed in 2007 May during its close Earth approach with the AKARI space telescope and in 2007 August with the Subaru telescope. A thermophysical model analysis of the obtained data resulted in a radiometric diameter of 0.92$\pm$0.12km and a visual geometric albedo of 0.063$^{+0.020}_{-0.015}$. The geometric albedo is typ...
