Eventually Sirius and it's enormous (8 ly radii) Oort cloud will move on. btw; your link "Asteroid_impact_mission_targets_Didymo" is broken. http://en.wikipedia.org/wiki/65803_Didymos http://en.wikipedia.org/wiki/AIDA_%28spacecraft%29 http://www.esa.int/About_Us/GSP/Aste...argets_Didymos |

Robotic tripod landers packing a sufficient cache of fuel or energy for ion thrusting, seems doable. They could apply a very good test for this thrust reaction method, as to modifying the weird orbit of our second moon. Otherwise, a tethered tug applied to our moon should be the case of doing what's right, by assisting it to move further away and slowing its orbital velocity at the same time, in order to part it within Earth L1. |
