Dec 5, 2015 at 19:40 comment added HopDavid @SF. From L1 nudge towards the moon. object will fall into an ~60,000 x 5,000 km lunar orbit. While ellipse's line of apsides remains the same, location of EML1 and EML2 rotate. At 3rd apolune, spacecraft finds itself in the neighborhood of EML2. If timing is right it can fly from EML2 and out through SEL1 or SEL2.
Dec 5, 2015 at 17:38 comment added SF. @honeste_vivere: still doesn't explain the trajectory for heliocentric... L1 is a saddle type point, meaning only two preferred departure directions, and stable balance in direction perpendicular to these. Both departure directions aim straight at Earth and Moon.

Dec 5, 2015 at 9:14 comment added SF. @HopDavid: How can L1 lead to escape? What would be the trajectory for that?
Dec 5, 2015 at 3:33 comment added HopDavid Nudging from EML1 can give a wide variety of results: crashing into the moon, crashing into the earth, or expulsion from earth's Hill Sphere. Same goes for EML2. Nudging from EML3, EML4 and EML5 seems to result in longer lived horseshoe orbits that stay at a lunar distance from earth, sometimes appraching and then receding from the moon on the trailing side, sometimes approaching and then receding from the moon's leading side.
Dec 5, 2015 at 1:46 comment added kim holder Hm. The related question deals with L 1 and 2. The dynamics in the other three look different. To the extent the answer is probabilistic it would be the same for all of them, however the most likely outcomes must be different for L 4 and 5, and especially 3.
