Abstract
Solid particles present in the solar system derive from natural origin is termed -dust particles- in general. Dust particles are considered to be supplied from comets, asteroids EKBOs, satellites and planets, and some known as interstellar dust particle from outside the solar system. Since dust particles are thought to be closely related with the evolution of the solar system, study of these materials provides us with crucial information about the history of the solar system. This paper reviews major results of recent studies on dust particles, which utilize space environment experiments. In-situ dust measurements exposed in space environment and dust aggregation experiment under the micro-gravity condition are reviewed in detailed here.
