Abstract	Visible and near-infrared reflectance spectroscopy has been a useful method for remotely detecting mineralogy of planetary surface materials. However, there have been two problems in the analysis. One of these is space weathering, other problem is multiple broad bands of minerals. The purpose of this study is to solve these two problems maiking model. And this new model has been applied to the visible and near-infrared reflectance spectra of asteroids 6Hebe, 433 Eros, and 25143 Itokawa.
Keywords	asteroid, Visible and near-infrared reflectance spectrum, space weathering, Modified Gaussian model
