摘要:	Small solar system bodies are thought to be remnants of planetesimals from which the major objects in the solar system formed. Because of their primordial characteristics, it is important to know the basic properties of the small solar system bodies, such as size distribution, spatial distribution, physical properties and chemical composition in order to understand the origin and evolution of the solar system. This program utilizes Lulin Observatory in Taiwan, Japanese space infrared telescope "Akari", and the Pan-STARRS in Hawaii to provide comprehensive understanding of small solar system bodies. The Pan-STARRS is a project to monitor the sky visible from Hawaii every week to detect transient objects. The Pan-STARRS database is used to search for comet-asteroid transition objects and young collisional family members, and to construct the phase angle dependence of the brightness of asteroids. Scientifically interesting objects are extensively followed up by 1-m and 2-m telescopes at Lulin Observatory to study the surface properties of objects. The whole-sky-survey data of space infrared telescope "Akari" is used to estimate the size and albedo of more than 5000 asteroids. This program tries to accumulate basic properties of asteroid and establish the standard database for coming decades. 研究期間 : 9808 ~ 9907
