most planets and moons could be mathematically ruled out as the source of the meteorite,and if its age showed a short span of time since it was formed,this would prove that it must have came from further away without having existed long enough to do so sujesting time spent at a significant % of light speed, the search could then be made further away for similar densitys of matter ,ruling out thoes bodys that dont have that type of rock , mineral, or metals etc in them using available raidio telescopes and hubble, if no suitable doner were found it would sujest a longer span of time near light speed....ive got to ly down my my head is exploding aaahhhhhhhhhh pop!!!!!
