1864 Daedalus

This Apollo asteroid has been classified as an SQ-type by Tholen (1989). Its rotational period, [FORMULA] hours, has been determined by Gehrels et al. (1971) and this object shows a large amplitude (0.85 mag) of the lightcurve, which implies a very elongated shape. The estimated diameter is about 3 km. No previous spectral information is available on this asteroid and the spectrum we obtained (Fig. 3) shows a trend similar to that of S-type asteroids. Anyway, in this case, as reported in Fig. 3, there is a good match between the spectrum obtained and the laboratory spectra of L4-type OC.
