Fig. 1
Comparison of linear polarization degrees of 1998 KU2 and other bodies in the solar system in the red region (about 650 ± 50 nm). The open circles indicate data corresponding to 1998 KU2 . Other symbols denote data for Ra-Shalom (open square), Phobos (open diamond), Deimos (open triangle), 2P/Encke (plus), and 209P/LINEAR (crosses). The solid line corresponds to high-polarization comets (Levasseur-Regourd et al. 1996).
