The Exploration and Research Advance of Small Bodies in the Outer Solar System
摘要
Abstract
The small bodies in the outer solar system mainly include Centaurs and trans-Neptunian objects,which contain methane,water ice,ammonia and so on,representing the most primitive bodies of the solar system.Studying the properties of small objects can help understand the origin and evolutionary history of the solar system and reveal their relationship with water and life on Earth.Currently,deep space exploration has entered a new era of vigorous development.The New Horizons spacecraft will continue to fly to the Kuiper Belt to visit these distant objects.China is also carrying out science missions to explore the boundary of the Solar System.This paper introduces the exploration and research advance of small bodies in the outer solar system from the aspects of detection history,albedo and size distribution,orbital distribution,color index,spectral properties,etc.,with a focus on their visible light,near-infrared and mid-infrared spectral properties.Future research trends will be discussed to provide support for China's missions to explore the outer solar system and icy moons.关键词
