Evaluation of the asteroid material composition by reflectance spectra using meteorite analogues

Abstract

The MATLAB program was developed to estimate composition of the asteroid material. The program models reflectance spectra of asteroids using reflectance spectra of meteorite analogues. Modeling results and estimation of the material composition for 10 asteroids (1 Ceres, 4 Vesta, 51 Nemausa, 65 Cybele, 102 Miriam, 250 Bettina, 266 Aline, 379 Huenna, 704 Interamnia, 1474 Beira) are discussed. A good agreement between the model spectra and the asteroids reflectance spectra is achieved for a number of asteroids (1 Ceres, 4 Vesta, 51 Nemausa, 250 Bettina, 704 Interamnia)
