　　摘    要：Near-Earth asteroids and comets (collectively called the "Near-Earth Objects" or NEOs) play a key role in shaping the geological and biological history of the Earth. Recent studies have shown that NEO impacts are common in the near-Earth environment (Strom et al. 2005) which support the idea that the development of life on Earth is tied to the life-essential materials delivered by NEOs. As such, understanding the physical and dynamical properties of NEOs has long been of great interests in the community. In the recent years we have seen a number of highly successful in-situ exploration missions to NEOs and other small bodies, each has provide tremendous insights into the properties and evolution of small solar system bodies. Meteor astronomy, on the other hand, provide a possibility to explore NEOs without the cost of a deep space mission. I will overview the recent progress in meteor astronomy and discuss its prospect in the exploration of small solar system bodies.
