Grain alignment with respect to magnetic fields by radiative torques recently became a favored mechanism to explain the grain alignment in various conditions, e.g. in molecular clouds, reflection nebulae. In Zodiacal cloud, dust grains can be aligned with interplanetary magnetic fields due to the Solar radiation, such that the solar light reflected on aligned grains get circularly polarized. We present new results on circular polarization (CP) of scattered light from Zodiacal cloud and comets. We show that the magnetic field geometry can be constrained by studying the variation of CP with the elongation angle and compare it with observation data. We expect that polarized emission from Zodiacal dust plays an important foreground that should be treated properly in CMB polarization experiments. We find that polarization for light reflected on aligned grains in comet coma is consistent with observation data.
