Parent bodyParent Bodies Designations– Actual source body of meteorite– Generally requires a sample return missionProbable Parent Body– Correct mineralogy– Delivery mechanism providing appropriate fluxPlausible Parent Body– Correct mineralogy– Reasonable delivery mechanismPossible Parent Body– Correct mineralogy or Reasonable delivery mechanism
Delivery StagesEjected from asteroid surfaceDelivered to transfer orbit– Generally via a resonanceEncounter the Earth before:– Collisional destruction– Impacting the Sun or other body– Ejection from Solar SystemSurvive atmospheric entryGet recovered
