Asteroid 4179 Toutatis has been extensively observed during its 1992-93 close encounter with the Earth. We observed it spectroscopically in the visible at the ESO-La Silla Observatory (Chile) and at the Asiago Observatory (Italy). Analysis of low-resolution spectra of the asteroid taken at the Asiago Observatory (Italy) has revealed typical behavior of an S-type object with no evidence of surface composition variations.

Abstract
Asteroid 4179 Toutatis has been extensively observed during its 1992-93 close encounter with the Earth. We observed it spectroscopically in the visible at the ESO-La Silla Observatory (Chile) and at the Asiago Observatory (Italy). Analysis of low-resolution spectra of the asteroid taken at the Asiago Observatory (Italy) has revealed typical behavior of an S-type object with no evidence of surface composition variations.
