How To Keep Orbits Around The Triple Asteroid System 2001SN263?

Asteroids are celestial bodies much smaller than planets. They have irregular shapes and very weak gravity fields. Space missions around an asteroid can be challenging due mainly to the large disturbing forces – such as those coming from the solar radiation pressure and from the asteroid non-spherical gravity field – actuating in the surroundings of
