Abstract

Context. Primitive asteroids contain complex organic material and ices relevant to the origin of life on Earth. These types of asteroids are the target of several sample-return missions to be launched in the next years. 1999 JU(3) is the target of the Japanese Aerospace Exploration Agency's Hayabusa 2 mission. Aims. 1999 JU(3) has been previously identified as a C-class asteroid. Spectroscopic observations at longer wavelengths will help to constrain its composition. Methods. We obtained spectroscopy of 1999 JU(3) from 0.85 to 2.2 mu m, with the 3.6 m Telescopio Nazionale Galileo using the low-resolution mode of the Near Infrared Camera Spectrograph. Results. We present a near-infrared spectrum of 1999 JU(3) from 0.85 to 2.2 mu that is consistent with previously published spectra and with its C-type classification. Conclusions. Our spectrum confirms the primitive nature of 1999 JU(3) and its interest as target of the sample-return mission Hayabusa 2.
