摘要:
本文讨论引力按重要性排序可被忽略情况下的小行星远距离轨道设计及动力学。航天器的运动是太阳引力和太阳辐射压力的函数。航天器和小行星之间的加速度在太阳和小行星这两个物体之间形成了特殊的相对动力学关系,可为航天器提供停驻在小行星附近和利于观测的轨道条件。本文完整解决了小行星处于圆形日心轨道这一较简单情况,也考虑和阐述了椭圆轨道情况,并取得了一些初步结果。

Distant Proximity Orbits about Asteroids
Daniel Scheeres
Abstract:
This paper considers the design and dynamics of spacecraft distant from an asteroid, whose gravitational attraction can be neglected at leading order. The motion of the spacecraft then is a function of solar gravity and solar radiation pressure. The differential acceleration between the spacecraft and the small asteroid creates a unique relative dynamics between the two bodies, and provides the spacecraft certain orbits that will remain in the vicinity of the asteroid and which could be used advantageously for observations. The current paper completely solves the simpler case when the asteroid is in a circular heliocentric orbit. The elliptic case is also considered and formulated, with some initial results identified
