Asteroid 4179 Toutatis has been extensively observed during its 1992-9
3 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 asteroi
d taken at the Asiago Observatory (Italy) has revealed typical behavio
ur of an S-type object with no evidence of surface composition variati
