Based on the primary orbital relation among sun, earth and space object, the mathematic model of space object sunlighting problem is made. Effects of various parameters and their change field, period, etc. for space target sunlighting are analyzed. As the most familiar satellite orbit, the rela-tion between the sunshine factor of the circle orbit and its semi-major axis is discussed, and whole orbital sunshine equation of circle orbit is made. Furthermore, many applications of sunlighting characteristics of space objects in space activities are studied, such as the optical detecting and the tracking of space targets, the sun sensor, the radiation pressure effect and the space solar power system. And developing aspects, key techniques or technical characteristics of these applications are analyzed. These results will help to study practical problems further.
