Karazin popup.description2 Objects of investigations: near-Earth asteroids (13553) 1992 JE, (66251) 1999 GJ2 and (100085) 1992 UY4. Purpose of the project is photometric and polarimetric observations of the selected near-Earth asteroids (NEAs) for the purpose of determination of their physical properties and characteristics. Methods of research: CCD-photometric and polarimetric observations, processing and analysis of data. During 28 nights the CCD-photometric observations of near-Earth asteroids (13553) 1992 JE, (66251) 1999 GJ2 and (100085) 1992 UY4, and during three nights the polarimetric observations of NEA (100085) 1992 UY4 were carried out. The lightcurves, absolute magnitudes, color indexes, rotation periods, sizes, shapes, composition types, phase curves of brightness and polarization and other physical characteristics of these asteroids have been obtained. Most of the results were obtained for the first time, that is why they are of great interest from the point of view of both fundamental science and the asteroid hazard problem. They are also very useful for planning and realization of the radar observations of these NEAs and for the creation of their physical models. The obtained lightcurves will be included to the international database "Asteroid Photometric Catalogue". Product Description popup.authors popup.nrat_date 2020-04-02 Close
