Results of Polarimetric Observations of Near-Earth Asteroid 433 Eros

Abstract

Abstract Near-Earth asteroids are of great importance for science. We present the results of polarimetric observations of near-Earth asteroid 433 Eros. Previous polarimetric observations of this asteroid did not cover a range of phase angles less than 9°. We were able to measure the degree of linear polarization of asteroid 433 Eros at a phase angle ≈4.°8. The data obtained made it possible to determine the parameters of the negative branch of the degree of linear polarization of this asteroid, such as the magnitude and position of the polarization minimum in four spectral ranges.
