A statistical dynamical study of meteorite impactors: A case study based on parameters derived from the Bosumtwi impact event

摘要

The study of meteorite craters on Earth provides information about the dynamic evolution of bodies within the Solar System. the Bosumtwi crater is a well studied, 10.5 km in diameter, ca. 1.07 Myr old impact structure located in Ghana. The impactor was ~1 km in diameter, an ordinary chondrite and struck the Earth with an angle between 30° and 45° from the horizontal. We have used a two phase backward integration to constrain the most probable parent region of the impactor. We find that the most likely source region is a high inclination object from the Middle Main Belt.
