In the solar system, it is reasonable to regard the motion problems of the major planets, minor planets and satellites (including natural and artificial ones) as the perturbed two body problems, and the perturbing sources are mainly the third body.
在太阳系中,大行星、小行星和卫星( 包括自然卫星和人造卫星) 等对应的运动问题,都可以处理成受摄二体问题,而摄动源又多为第三体。
